clinic in pennsylvania. jon: what an awful story. i'm jon scott. police are still trying to figure out who the gunman is and why he opened fire at the university of pittsburgh clinic. it happened yesterday afternoon. they say the guy walked into the clinic lobby, carrying two semiautomatics and started shooting. seven people, hit in all, one of them was killed. police now identifying the victim as a 25-year-old staff member, michael schab. the gunman was shot dead apparently by campus police. right now the medical examiner's office, saying he had no i.d. on him and running his fingerprints through a nationwide data base turned up no clues. people in this community are stunned by what happened. >> they weren't able to move anywhere. everybody had to stay on their floor and stuff. >> never happened in our school, in this area. i'm just like so worried. >> i don't know what the security is like above the first floor right now. that's as far as i've gone. jon: pittsburgh make lake ravenstahl joins us. any new information on who this gunman was or why he did this? >> at this point, we still have not identified the gunman, nor do we know his motive for entering the facility yesterday. it was truly a senseless and sad and tragic day in our city. the investigators obviously continue their work and as we continue to gather information we'll share it with the public. i don't know jon obviously it was a psychiatric clinic. anybody who would do something like this probably needed psychiatric help. he was completely unknown to the clinic or the staff there? >> again, that remains under investigation. at this point, it's unclear whether or not he was a patient of the clinic. there's not much known about him. as you mentioned, he had no identification on him, and at this point this morning, we've still been unable to identify the individual. hopefully that work will take place today, and perhaps we'll have an i.d., and then we'll be able to potentially figure out a motive. but the bottom line is this is just a tragic day for somebody to walk into a facility like that and open fire makes no sense, but i have to give credit to the folks involved from the employees of the hospital, to the public safety officials, for their courageous acts. the fact that only one person other than the gunman was killed is a testament to the ability of those folks to risk their own lives to save others', and we're very fortunate that only one person other than the gunman was killed yesterday. jon: it's really a tribute to the campus police and others who stopped this thing. >> it is. they were in the building within a matter of minutes, so the gunman entered the facility about 140 time p.m. yesterday afternoon, and literally, within minutes, the university of pittsburgh police officers entered behind him and were able to obviously kill him before he killed any other innocent victims. there were also seven others that were wounded. to the best of my knowledge this morning, all of them will take a healthy recovery, and we're very, very blessed for the heroism of the police department. onjon that is i guess a small window of good news in this tragic and awful story. mayor luke ravenstahl, thank you for joining us. >> thank you. jenna: from one developing news story to another we have this fox news alert. we are going to take you to dallas. do we have a live picture of that? there we are, a live picture of dallas where we are hearing first reports of what's being described as an armoured car robbery, reports of two people shot at a western union in dallas, texas. that's all the information we have at this time. it's a story we'll continue to watch on "happening now" but that's the report an armoured car robbery in dallas. more on that as we get it. in the meantime we're going to turn to d.c. there are growing concerns among some republicans that the grueling primary may have hurt their chances of winning the white house in november, but could the fears be overblown, even if the field does not narrow soon? try comparing it to the priewzing race between president obama and hillary clinton four years ago, some analysts believe that showdown actually made the eventual nominee, the president, a stronger contender in the general election. chief correspondent james rosen has more on this. >> reporter: you've seen the headlines, negative campaign tarnishes candidates and all the handwritinging about how the quote unquote bruising primary contest has been primed by sharp attacks, this quote from four years ago when hillary clinton and barack obama ran. indeed it wasn't until june june 2008 then senator clinton withdrew from the race and not until late june from the two appeared for this unity rally in ynty new hampshire. that exercise followed unkind suggestions by mrs. clinton that mr. obama was an empty suit and like minded suggestions that mrs. clinton was in the pocket of beltway special interests. >> that's the difference between me and my democratic opponent. my opponent makes speeches. i offer solutions. it's one thing to get people excited. i want to power you -- empower you. >> in this campaign, she has taken nearly double the amount from lobbyists than any democrat or republican running for president. that's not being a part of the solutions business. that is being in the business as usual business. >> reporter: democrats today cast the vitriol of the primary where charges of lying and plundering have been advanced, analogies of campaign ads show a predominance of activity in that matchup. what we will likely hear from the number two finisher in this cycle will likely parallel sentiments from then senator clinton, almost exactly four years ago today >> issue after issue, i think the democratic party will see that whatever differences general obama and i might have had during the primary campaign, they pale in comparison to to mccain and the republican party and i think that's a strong case in which we will be making with a unified front. >> reporter: and once again more than two months would pass before those remarks before clinton would concede to her rival and now boss. jen general an interesting dac -- look today, james, thank you very much. jon: for more perspective, steven hayes, writer for the weekly standard and fox news contributor. what do you think about that? does this ongoing battle between the republican candidates make the eventual winner stronger? >> i think there's an argument to be made both ways. on the one hand, you've got mitt romney, if he becomes the eventual nominee, who will have sort of been run through the gauntlet,o gauntlet as james explains, he will have identified supportners key states, they will have gotten out, gotten voters to the polls, they will have had a test run for what would be his organization in a general election. on the other hand there has been quite a bit of negativity. a lot of the main issues against mitt romney, and i would argue rick santorum if he were to become the nominee, have been raised and aired and repeated, and the general negativity around the race i think is not good for either one of those candidates and it shows up most especially in the approval ratings, the favorability, unfavorability ratings, of these candidates among independent voters. jon: so the name calling is hurting. >> i think it is. i think the biggest argument is that this is hurting. it's been negative, it's been long. they're baaing the heck out of each other, they're identifying these negatives, and overall, it's not a positive. jon: but you know, whoever wins is going to be going up against a president who -- i mean, we've just seen the unemployment numbers. they're still stuck well above 8 percent, and some say if you counted everybody who could be looking for work, it would be ten, 12 percent or more. is the nation going to reelect a president in that situation? >> yeah. no, i mean, i think that's a good point. i think this president is one of the most vul nrable incumbent presidents in recent modern political history, so there's no question that republicans can still win, and i think a lot of the sort of doom sayers saying oh, this is over, the president's far too strong, the issue set works to his advantage, i that's very premature at this point. the question is which of these republicans can emerge and then mount a serious general election campaign and take those issues to president obama. jon: so much of the election is decided by independents. you know, much has been made of the fact that mitt romney might not be the most conservative republican in the field. but independent voters aren't necessarily looking for a conservative republican, are they? >> well, it depends on the issues. on national security and foreign policy issues, independents skew toward the republican party on some other issues, they don't, but mitt romney will i think have an argument to make. he can use what's been a disadvantage in the primary to his advantage in a general election. but i think he's got another problem. he's also got to excite and energize conservatives that haven't been excited about his candidacy so far. so he's got these two challenges if he is, nangt in fact, the republican nominee, that he's going to have to solve. jon: i guess he has, what, about seven, eight months to get it done if he's going to be the nominee. we'll see what happened. stephen hayes, thank you. >> thanks jon. jen this next story is really starking -- sparking a huge debate, surveillance of muslims inside new york and outside as well by new york city's police. coming up, judge nao na napolitano weighs in. jon: it's been one year since an earthquake and tsunami devastated japan. a live report from one of the areas hardest hit. jenna: that video still takes your breath away, doesn't it. >> a terrifying armed robbery caught on tape. the details and words of a woman who looked down the barrel of a gun, next. >> we need to get information. i need to you breath for me. okay, did they have a weapon? >> no, she -- they lad a shotgun. >> they had a shotgun? e to "ho-" and hello to "whoa, yum." use campbell's cream of chicken soup to make easy enchiladas, cheesy chicken & rice, and other chicken dishes that are oh...so...whoa. campbell's. it's amazing what soup can do. fresher less processed foods introducing freshpet recipes so fresh the only preservative we use is the fridge freshpet fresh food for fido jon: a shocking robbery caught on tape. take a look at this surveillance vid fro a store? dartmouth, massachusetts, two masked men burst in, point ago shotgun at the woman behind the counter, ordering her to hand over cash and cigarettes, she manages to dial 911, scared out of her mind. >> what's the matter? >> i got robbed. >> okay, okay. are you okay? >> listen to me, listen to me. calm down. breathe. breathe. are you okay? we need to get information. i'd like to you breathe for me. did they have a weapon? >> they had a shotgun. >> they had a shotgun? jon: they had a huge gun but they didn't use it. the dispatcher managed to calm the woman down, police arrived on the scene quickly. they are still, though, serving for those -- searching for those suspects. jenna: this sunday marks one year since a magnitude nine earthquake rocked japan and a tsunami with the nuclear disaster, the worst since chernobyl. sixty thousand died and 3000 others are still missing at this time, piles of debris scattered along the northeast coast, one bustling -- once business ling business and residential areas are ghost towns. in the exclusion zone, near the crippled fukushima nuclear plant, it went from a population of 16,000 to just one person. the lone holdout is a 53-year-old farmer, who is defying the government to leave so he can feed and care for the animals left behind. that includes a few key animals we're going to introduce you. david piper is streaming live from japan with more. david. >> reporter: hi jenna. yes, we hanged to get into that exclusion zone yesterday. nothing really prepares you for what you're about to see once you pass those tight security check points. the landscape was strewn with the remains of cars and boats. that's because they haven't been ae to allow people in to clear up that area. and that's as we passed through village after village. of course there was nobody there, but they were eerily quiet. there's no domestic animals or farm animals, they've all been taken out because of the danger. also, at this time, they have managed to get a few search teams over on to the beach, very near to the fukushima plant, about a mile away. they haven't been able to search there before. they're looking for 49 bodies of local people. they're still unaccounted for. there's over nearly 4000 people still unaccounted for in total from this twin disaster. but when we left this area, we spoke to a few villagers, and they were actually being checked for radiation. they said they managed to go in there to check their homes, they are allowed in time to time, but they did say that they didn't think they would ever be allowed to get back in. and we also went to tepc osm, the company that runs the fukushima plant, we went to the offices in tokyo and a spokesman told me they really had no clue when this would be safe for those people to go back to their homes. jenna: unbelievable, still to this day. david, thank you. jon: a fox news alert. we're getting through information now on the robbery of that armoured car in dallas. harris has the latest. she's in our newsroom. harris. >> reporter: we want to alert everybody that these are live pictures via our affiliate kdfw, and you can see all of the response from the dallas police department. we do know, coming from local reports there, that the driver of this armoured vehicle that's now in the center of your screen had just pulled the vehicle up, when apparently there was a man waiting as the driver opened the door. apparently, that man opened fire. and then the driver opened fire, returned fire. so you have two people shot. you've got the driver of that armoured vehicle, truck, rather n. the center your screen, and the suspect of and both people reportedly have been taken to local hospitals and of course you see all the police officers on scene, trying to figure out what exactly -- exactly what steps to take, whether there was, in fact, a robbery. we don't know yet but we know about the shots fired in exchange. jon hair i. stay on it for us. >> reporter: will do. jon: the fight against unemployment turning to twitter. how tweeting might help some people actually find a job. hmm. plus we're going to talk to someone embedded with the navy's fifth fleet in one of the most important waterways in the world right now. the strait of hormuz. his insight, coming u dad, why are you getting that? is there a prize in there? oh, there's a prize, all right. [ male announcer ] inside every box of cheerios are those great-tting little o's made from carefully selected oats that can help lower cholester. is it a superhero? kinda. ♪ jenna: well, right now the strait of hormuz is one of the most precarious waterways in the world, gateway to the persian gulf where 40 percent of the world's oil passes through. on one side, you have saudi arabia, kuwait, iraq, the other blocking the strait of hormuz, even temporarily would cause one fifth of the world's oil supply to be bogged down and some predict the price of a barrel of oil could double to more than $200. our next guest is returning from a stay on the u.s.s. carl vincent, embedded with the navy fleet that polices the strait of hormuz. joining us is a foreign affairs columnist with the "wall street journal". nice to have you with us, bret. >> good to be with you. jenna: the story takes on more importance because of the ongoing discussions with iran and i understand while you were on the aircraft carrier you were being shadowed by an iranian ship. tell us about that. >> at the time i was actually and the u.s.s. bunker hill, which is the egypt-type cruiser that was the carrier's essort -- escort, and at a certain point through the morning haze, you could see off our star bird beam, about 3400 yards away, a dow, the dow are the ships of the area, mostly commercial ships, this one you knew was iranian because it was flying anan flag, it had a radar far too extensive for fishermen to own and it shadowed us and came within a mile. the officers going to the gulf for money years told me this is typical behavior on the part of the iranians. the worrisome thing is that there have been incidents over the last year in which the iranians have come very close to some of our capital ships and the fear is that even a small boat could do enormous damage to a very large u.s. ship. just think of the u.s.s. cole, back in 2000. gen jen sure. we've had people come on the show, different analysts, that have talked to us about what could actually lead to war with iran and some have pointed to the strait of hormuz and a miscalculation or sudden decision that could launch us into a bigger war with the country. i'm curious because we've talked so much about iran together on this show, having been to the strait of hormuz at this time in our history what are some of your observations now that you're back home and thinking about the situation with iran? >> the first observation that has to be said, we have a magnificent navy, certainly magnificent officers and sailor, highly competent, and nothing kind of can duplicate or replicate the experience of actually spending time out there with our -- with the sailors, with the pilots out there. on the other hand, when i was in the persian gulf, we really had four, five ships, major ship, in theater. so it of not a particularly large deployment. and i think this, to some extent, speaks to the downsizing of our overall military. twenty, 25 years ago we had close to 600 ship, now we have less than half that number. that's a significant effect. the third point is while the iranians are generally cautious around our boats, they do have rogue -- or it seems to be that they do sometimes have rogue elements in their navy, in the naval component of their revolutionary guards corps who may be tempted to carry out lone acts against our ship that could precipitate war. the iranians are thought to have about 5000 mines. that could close the strait of hormuz pretty quickly. jenna: that's a scary thought to think about, especially because the aircraft carriers and other ships carry so many of our men. quick thought, doug mcfarland was on our show and said if he could give the president any advice it would be to park aircraft carriers, more than one, off the coast of iran and just sit there. mitt romney had an op-ed piece in the "washington post" that said something similar this week. my question for you, is it about numbers? you mentioned the number of the ships an wanting to see them big, you know, versus small in a time like this, but is it about the numbers or is it about the real threat to use those ships if need be? >> well, you know, there's a saying in the military that quantity has a quality all of its own. now, there was also the abraham lincoln, another carrier parked outside of the arabian sea doing operations for enduring freedom for afghanistan. that's also part of the fleet. but that was on the other side of the strait of hormuz. i have no doubt that we have a navy and one admiral after another made this clear to me, that it's highly capable and could take on the iranians if we were -- this they were -- if they were called to do so, but nonetheless, when you have relatively few capital ship, each of those ships becomes more important to your overall fleet, and more vulnerable to an asymmet rical type of attack and we need to train very carefully and plan very carefully against that possibility. jen you give us a valuable perspective. you figure you're just going to retire
