The case raises the issue of gun violence on college campuses. The protective measures which now need to be taken. For more i spoke with anthony roman, the head of a Security Firm in new york. Anthony, thank you for joining us. There seems to be so many shootings at colleges and schools in america in recent years. What sort of precautions do colleges now have to take to avoid the sort of incidents . Colleges have evolved very much as communities have evolved in the United States to deal with the new phenomenon of mass shootings. Fundamentally, the police campus, theon campus police, are Sworn Police Officers with full police powers. They now respond in a very aggressive fashion to any shooting or killing situation. Precolumbine, the Police Department would wait for special Tactical Units known as tot or Emergency Services get there prior to helping with the assault. Tactic is topolice proceed in if at all possible to protect as many lives and contain the situation as much as possible. That is the biggest change. Jane the police and swat teams are on the scene at ucla very quickly in huge numbers. How do they prioritize this type of response when i have to deal with so many other emergencies . Tohony they are trained participate in interdepartmental response scenarios. There are sufficient personnel when multiple Police Departments come together to offer Emergency Response and tactical officers just for this kind of scenario. All of that is thought out in advance. The logistics are prepared. The communities are well protected in terms of the usual services that police and ambulances and hospitals provide , as well as providing the capabilitiesal required for the emergency situation on campus. Jane you said that this is a relatively new phenomenon, the notion of mass shootings. Mass shootings. It seems like it is an ingrained part of American Culture now. As a parent, how do you prepare your child without traumatizing them . Anthony we have to be prepared globally. We have seen the events in paris, spain, london, the middle east. This has become a worldwide phenomenon. Of massseen acts violence before, but not at this great level of concentration in such a short time. What we need to know is we need to be aware of our surroundings at all times. We have to have a plan. We have to think about what if. What if there is a shooting or act of violence in our area. In the United States, the department of Homeland Security recommends several courses of action. One, be aware of your surroundings and exits. Plan your escape route in advance for any emergency. If you have the opportunity to run and escape, take that opportunity. Do it with all dispatch without hesitation. If you cannot run, hide. The best places to hide would be in offices, classrooms, or someplace with a door you can lock. If that is not possible and you are confronted by a gunman or someone with an act of violence within close proximity, fight for your life. Jane on that note, thank you for joining me. Reparation, as you say, is the key. Anthony thank you. Confirmed what many have suspected for weeks. The socalled Islamic State is using civilians as human shields as the iraqi army closes in on falluja. 20,000 children are reported to be dire with no aid getting into the city. The offensive has been underway for 10days. The closer he gets to falluja city, the tougher the battle is becoming. The southern near side of falluja the advancing Government Troops were surprised by a ferocious counterattack by the i. S. Fighters. They have had two years to prepare a network of defensive titles and provisions defensive tunnels and provisions. Thankfully we were able to dismantle explosive devices, destroy earth mounds, and damage tunnels. Most of it is under the control of counterterrorism forces. Correspondent this is an area which the government claimed it captured several days ago. It is clearly not under control. Has snipers everywhere and suicide attackers add another deadly threat. To the northwest of the city, it seems to be mainly the iranian backed shia militia making the running. They are trying to surprise the i. S. Fighters out of a township which has yet to be fully subdued. As a ring of steel with which the government is trying to encircle falluja is not yet in place. Only then can the attacking launch a final offensive into the densely builtup city where the trapped civilians are being used by i. S. As human shields. In the ongoing conflict in neighboring syria with heavy overnight airstrikes causing damage and many deaths in the rebel held northern city. Workern and an aid affiliated with save the children were those reported killed in a bombing in which on russianre blaming jets. The partial truce announcement in february is rapidly unraveling, with no end in sight for a disastrous conflict that has raged on for fiveyears. Bbc news, baghdad. Jane at least 10 people were killed after militants launched. N attack in mogadishu a car bomb exploded at the gates of the Hotel Ambassador and gunmen stormed the hotel, which was rented by politicians. The Islamic MilitantGroup Alshabab say they carried out the attack. A humanitarian aid convoy has reached a besieged syrian town for the First Time Since it was surrounded by Government Forces in 2012. They brought medicine, baby milk , and other supplies. It is home to 4000 people. A convoy also reached a nearby town. Primary is notl over. Hillary clinton and donald trump are already taking the gloves off. Mrs. Clinton called the Presumptive Republican nominees university a fraudulent scheme. Before she takes on mr. Trump, she has to get through Bernie Sanders. How far will her fellow democrat question posed in this weeks time magazine. Bernie sanders has gotten further than anyone, including him, actually expected. What are his options . He is not going to win the nomination . He will not win the nomination, but that does not mean he cannot remake the Democratic Party in his image. He will go to philadelphia with a list of demands he thinks he can extract, including a higher minimum wage, emily paid leave family paid leave, and rewriting the rules for the nominating process. All of which can happen. He has secured 5 seats on the platform committee. Clinton has 6. He only has to win over one to remake the party. Supporters are also looking at him for guidance. Theyre looking at him to say not only vote against trump but vote for Hillary Clinton. Has a long way before he is willing to say that. Jane your article suggests he was hurt and surprised by the level of attacks from the clinton campaign. How much of the decision to stay in the fight is personal . Getting out of the race is one of the most difficult choices a candidate makes. He is not ready to go there. He has scores he wants to settle. He and Hillary Clinton were friends in the 1990s. He has a framed photograph of them working on health care together from 1993. He thought they were friends. Initially, he told donors and others not to attack her personally and go after her email. She will probably be the nominee, lets not willed her. That will go out the window now. Lets not wound her. That will go out the window now. At her hills and suggesting her paid speeches to wall street were coming from a place of corruption. That she is not trustworthy or likable. This goes to damage her and so doubts and misgivings among supporters. Many of whom are new to politics. Hillary clinton needs to defeat donald trump and the newcomers coming out for him, she will need the Bernie Sanders supporters. At the moment, they are not ready to be with her. Jane republicans are rallying behind donald trump to a point, but there is talk of an independent candidate. How likely is that . It will be difficult. A lot of the deadlines have passed. The Libertarian Party have picked their nominee. Mechanically, it is almost impossible. The only option for the antitrump policies are to get a couple of candidates to deny both of them. Jane you are watching bbc world news america. Still to come on tonights past. M, clues to the archaeologists have discovered the oldest handwritten documents ever to be found in britain.

From any of us, the Movie Star Wars may be seen as a battle of good versus evil. Think again says one of americas greatest legal scholars. Nearly 40 years after the first sunsteinreleased, cass themes fromer technology to thomas jefferson. He has written about it in his new book the world according to star wars. He joined me a short time ago. You are one of the top legal minds in america. How did you write a book about star wars . Cass if you told me a year ago i would write a book about star wars, i would not believe you. It would have been more likely i would have become a ballet dancer. My fiveyearold toy got obsessed with star wars. His obsession with star wars got me thinking how did these movies come about . Why does it appeal to five years old . Why is it the saga of our time . Why are people in denmark, the thailand focused on star wars . When i asked those questions, i was hooked. Jane use a there are 13 different ways to look at star wars, from feminism to constitutional law. You could say that about lord of the rings or harry potter. What makes star wars special . Cass it draws on myths and religions of multiple kinds. George lucas, the maker of the basic idea of star wars, is selfconscious about this. You can see this unity, judaism, many others. It distills them into an essence. It gives them to think smiths and religion did not have. A sense of effervescent giddiness, which is stored lucas own term for the movies. He confesses he himself is not effervescent or giddy at all. One thing it draws on is Anglo American traditions and not world culture, freedom of choice. One reason the movies get under peoples choice is whether you identify with princess leia, han solo, obiwan kenobi, Luke Skywalker i can name many names, whichever one you identify with theres a crossroads moment where they make a choice that alters the choice of their life. All the talk about destiny, valorize is inhs the movies, but confounded at every turn. Jane who do you identify with . Cass i would like to identify with han solo. Jane a lot of movies could say the same thing. Do we actually learn anything from star wars . Cass i think so. The most important lesson, and enduring lesson, is whatever you have done that you are not proud of, maybe involving your career or relationship that went sour, redemption is always possible. Person in the galaxy, darth vader, can in the end choose to save his son and in that way save his own soul after a lifetime of terribleness there is a lesson there for all of us. The freedom of choice and redemption ideas are closely aligned. Also about children and parents. If your kid loves you it is fine. If you come in the end, are willing to take lightning bolts of the emperor, or the equivalent, to protect your kid, you have something to be proud of. Jane is there any way of using star wars to interpret what is happening in the u. S. President ial election . Cass absolutely. Particular, in though also the original beloved trilogy, they are focused on the risk of losing democracy to a strong leader. Certainly in circumstances where the legislature and parliament, or congress, is paralyzed. Certain people will think i want make, fill who will in the blank, great again. Many parts of europe, other parts of the world, certainly in the nine at states. Whether you like or dislike mr. Trump, there is no question at the idea of a tough guy has appeal. In some circumstances that can move a nation in the right correction, but it is often dangerous. Jane i will never look at star wars in the same way again. May the force be with you. Cass and with you. Jane the earliest known handwritten documents to be found in britain have been discovered in the heart of london.
