the sun is showing no mercy. the mercury soared again today in the central and eastern united states, with temperatures in the 90s and over 100. the weather service put out a heat warning for much of the region, including illinois. the temperature in chicago hit 103, breaking a record that had stood for more than a century. and the heat wave may be aggravating a crime wave. there were 22 more shootings in chicago overnight, five of them deadly. so far this year, the city has cid 270 homicides. dean reynolds has more now about crime in the heat of the night. >> reporter: the victims of chicago's increasingly bloody summer are trapped now between a plague of gangland violence and the onset of triple-digit heat. ten-year-old kitanna peterson was out late tuesday night on the far west side playing in a ntre hydrant when she was shot. a stray bullet went through her anist and abdomen. >> you know what kind of man do that? a fool. he'll be caught. >> reporter: many of the nearly two dozen wounded in the past 24 hours were, like kitanna, s weoors and seeking relief from the scorching temperatures, at what turns out to be exactly the wrong time of day. 00 ause, statistically, 9:00 p.m. to 2:00 a.m. are the most murderous hours in this city's neighbt neighborhoods where gangs thrive. jenz ludwig runs the university ns chicago crime lab. rsity of chicago crime lab. >> crime is, unfortunately, very concentrated in lowest income neighborhoods in the city. those are the neighborhoods where people are least likely to have air conditioning or adequate air conditioning. >> reporter: the chicago temperature this afternoon reached 103 degrees. in fact, it's gone over 100 for three straight days here. and researchers say that kind of heat triggers chemical changes in our bodies, such as an increase in testosterone that can boost aggressiveness. >> that kind of problem is particularly dangerous in an environment when you have a lot of gangs and a lot of guns on the streets. >> reporter: now, 10-year-old kitanna peterson is in the hospital now, recovering from her wounds. and this afternoon, we actually had a brief shower, which sent the thermometer down just a bit and provided some relief from the heat. but anthony, providing relief from the violence will require, i'm afraid, more than a few raindrops. >> thank you, dean. the heat is contributing to a record drought. a report out today shows moderate to extraordinary drought conditions in nearly 56% of the continental u.s. that's the highest in at least 12 years. president obama set out today on a two-day campaign bus tour that will take him from ohio to western pennsylvania, two battleground states that will decide which way the election goes. we have two campaign 2012 reports tonight. first, norah o'donnell with the president. norah? >> reporter: anthony, we're here in northern ohio, which is part of america's rust belt, where the president is trying to make the case that it's his policies that have saved jobs. but you also get the sense that he's here in order to make sure that low voter enthusiasm doesn't cost him a second term. >> i'm betting you're not going to lose interest. i'm betting you're not going to lose heart. >> reporter: traveling in a bulletproof bus nicknamed "ground force one," the president is visiting the heavily populated communities of northern ohio. because these are all areas which voted democratic in 2008. and he will need that same strong voter turnout to win the state again. this is a region dependent on auto manufacturing. the president visited a nearby chrysler plant just last year. today, he boasted that same plant is now hiring, and he credited his $82 billion auto bailout, something mitt romney opposed. >> when the american auto industry was on the brink of collapse, more than one million jobs were on the line. governor romney said we should just let detroit go bankrupt. >> reporter: the president is also hoping that many of ohio's middle-class voters will respond to his campaign's efforts to paint mitt romney as someone who sent jobs overseas when he lead the private equity firm bain capital. >> governor romney's experience has been in owning companies that were called "pioneers of outsourcing." that's not my phrase-- "pioneers of outsourcing." my experience has been in saving the american auto industry. >> reporter: and anthony, in what you might call a well-timed move, the president chose this state to make the announcement that his administration is taking on china for imposing what they call unfair trade fees on over $3 billion worth of american-made cars, cars like the jeep wrangler made nearby here in toledo. >> norah, thanks. and later in the broadcast, chip reid in china will tell us about the chinese love affair with american cars. mitt romney is in new hampshire. jan crawford talked with him yesterday about the supreme court's health care ruling, among other things. tonight, she has more of that interview. jan? >> well, anthony, we've seen the president hit romney hard for a while about his work at bain capital. and in our interview, i ask him whether he thought those attacks would resonate and how he planned to respond. >> he's in a real tough spot. he's grasping at any kind of straw he can find. and the reality is the american people can make their own assessment of whether the economy has gotten better under president obama or not. we have now 8.2% unemployment in america. >> reporter: is that the new normal? >> it may be under this president, but i think we can do better, a lot better. the president predicted that we would be at 5.6% unemployment now. we have millions and millions of more americans unemployed than what the president predicted. the american people want to see someone who can get this economy going again, and create jobs for their kids coming out of high school and college. get people off the unemployment line. that's what i know how to do. that's what i want to bring to america. and this president, having failed to do that in the way he promised, now is looking for some way to hang on to his job. and i think in the final analysis, it won't work. >> why not? >> because the american people want someone who can get this country going again. >> and you don't think this president is, but why do you think you can convince the american people, and how do you change that impression that some people have of you? >> the people of america will stop and say, "is my life better because of this president? did his policies get us back to work? did they improve our lives? and if not does, mitt romney offer different answers with a different possibility for us." and the question is, of course, that's why i'm in the race. i laid out what i do to get this economy going. and as long as i continue to speak about the economy, i'm going to win. i'm just not going to grab at the attacks he throws out there, spend all my time talking about that because you know what? in the final analysis, people want to know who's the president that will make my life better and keep america strong? >> reporter: now, romney's confidence is not shared by some prominent conservatives who are saying to win, he just needs a bolder vision and maybe some new campaign staff. but regardless of what those conservative critics are saying, romney today can point to the best fundraising month for either candidate in this campaign. in june, anthony, he raised more than $100 million. >> impressive, jan. thank you. french investigators put out their final report today on the crash of air france flight 447. all 228 people on board were killed when the jet mysteriously plunged into the atlantic in june of 2009 en route from brazil to paris. it took nearly two years to recovery the flight recorders. mark strassmann now with the story they tell. >> reporter: air france flight 447's 38,000-foot plunge was a preventable disaster. the airbus a-330 flew into a storm at night. its speed sensors malfunctioned, which caused the auto-pilot to shut off. the captain was on break in the main cabin, and cockpit transcripts show the copilots became overwhelmed. the more junior one was actually flying the plane. the other copilot asked what is happening. "i don't know, i don't know what is happening." the junior pilot caused a fatal mistake by twice pulling up on the plane's nose, causing it to fly so slowly, it was about to stall. they both ignored stall warnings that sounded 75 times in the cockpit. the more junior copilot said, "i don't have control of the airplane anymore now." a minute and a half after the auto-pilot disengaged, the captain finally returned to the cockpit, but he never took control of the plane. "what are you doing," he asked? it was too late. three and a half minutes after the cockpit crisis began, the aircraft slammed belly first into the ocean. cbs news aviation and safety expert captain chesley "sully" sulenberger took us into an airbus simulator to help us understand the copilot's blunder. do you understand why he would pull the stick all the way back, when he should have been doing exactly the opposite? >> it's difficult to explain that. i just don't know why he did that. >> reporter: and there's nothing to you that makes sense on... on any experience or intellectual level about pulling back when you should push forward? >> no. >> reporter: nothing at all? >> sullenberger says, even without the speed sensors and auto-pilot, the flight crew should have been able to save the plane. >> theoretically, it was possible to still fly the airplane under those conditions. >> reporter: challenging but manageable. >> yes. >> reporter: in their final crash report, french authorities made 25 separate recommendations with a clear focus on pilot retraining, including training exercises dedicated to manual handling of stall recovery, including at high altitude. an airbus statement said today the company had already started working to strengthen requirements for pitot probes, the air speed sensors that malfunctioned aboard the flight. anthony, aviation experts say the air france plane flew into a perfect storm of bad weather, mechanical problems, and pilot weather. >> mark strassmann. thanks, mark. the mortgage company that gave out discount loans to influence congress. a judge sets a new, higher bond for george zimmerman in the trayvon martin killing. and a fireworks display over quicker than you can say "rocket's red glare." when the "cbs evening news" continues. s. what makes the sleep number store different? you walk into a conventional mattress store, it's really not about you. they say, "well, if you wanted a firm bed you can lie on one of those. we provide the exact individualization that your body needs. wow, that feels really good! once you experience it, there's no going back. hurry in now for our lowest prices of the season. save $300 to $1000 on selected sleep number bed sets. final days! sale ends sunday. only at the sleep number store, where queen mattresses start at just $699. here at the hutchison household. but one dark stormy evening... there were two things i could tell: she needed a good meal and a good family. so we gave her what our other cats love, purina cat chow complete. it's the best because it has something for all of our cats! and after a couple of weeks she was healthy, happy, and definitely part of the family. we're so lucky that lucy picked us.

>> when you're making their loan cost less-- no points, no fees-- then you're probably getting a level of favoritism that nobody else in the country was getting. >> reporter: the report says countrywide used that favoritism to keep the mortgage money flowing from fannie mae, and to fend off calls in congress to protect taxpayers against the rising exposure to toxic loans. >> unfortunately, i wonder if it really did work, because we didn't get the legislation that we really needed to do to clamp down on these types of loans. >> reporter: congressional leaders who got those discounted mortgages have all denied knowing they were getting favors. senator kent conrad and former senator chris dodd appeared on this broadcast in 2009. >> i did absolutely nothing unethical here. >> no special deals? no one ever offered one. >> reporter: both senators were cleared by the senate ethics committee, but the report displays cover letters and fax copies clearly showing references to the v.i.p. team or the v.i.p. unit, suggesting that even if officials did not know of the discounts, it was obvious this was special treatment. countrywide was highly skilled at expanding the use of the sub- prime loan. but anthony, we now know its other skill was having its way with congress. >> thanks, wyatt. mortgage rates have dropped to yet another record low. the average for a 30-year fixed is now 3.62%. the rate has set or matched record low levels ten of the past 11 weeks. a skyscraper is reaching new heights-- celebrating the shard when we come back. shard when we come back. over the south pacific in 1943. i got mine in iraq, 2003. usaa auto insurance is often handed down from generation to generation. because it offers a superior level of protection, and because usaa's commitment to serve the military, veterans and their families is without equal. begin your legacy, get an auto insurance quote. usaa. we know what it means to serve. my system gets why out of sorts it?

go west, hinrichs told us, to china's vast interior, where there are hundreds of millions of potential car buyers. most have never owned a car before. >> for many chinese, you have been riding a subway, riding a bike, a scooter or a bus for your whole life. but the experience people have for the first time having the freedom of transportation to go where they want to go is very special. >> reporter: and with all that cash changing hands, ford is staking out new territory in a country where an american car brings instant prestige. chip reid, cbs news, shanghai. >> the developers of the shard declared it europe's tallest building today. and if you were in london, the tower was pretty hard to miss. the celebrations included a laser light show. the tower is 1,016 feet tall and took three years to build. here's a celebration that was over before it began. in san diego, a computer glitch caused all the fireworks in a fourth of july display to go off at once. people had waited hours to see what was supposed to be a 20- minute show; it lasted 30 seconds. after the war, the healing. a place where military families can start over together, next. together. next. more suntans... lorida we had in alabama we had more beautiful blooms... in mississippi we had more good times... in louisiana we had more fun on the water. last season we broke all kinds of records on the gulf. this year we are out to do even better... and now is a great time to start. our beatches are even more relaxing... the fishing's great. so pick your favorite spot on the gulf... and come on down. brought to you by bp and all of us who call the gulf home.
