>>> a proud son of boston . former boston police commissioner, new york city and los angeles . these days a security consultant. bill bratton . i understand you are in the london bureau where among the subjects you discussed today was public event security. i.e. prime minister thatcher's funeral where you have 2000 vips attending. how are we going to defend and protect our public events when this goes off within the security cordon apparently surrounded by police, ems, volunteers at the finish line of your beloved boston marathon .

>> the reality as was evident today is you can't protect everything all the time. you try to prioritize, focus. you try to identify if there is a threat. boston police commissioner indicated there had been no threat received by either his department or to his knowledge federal agencies . the fact that homeland security is not advising other areas of the country to raise their terrorism level, terrorism concern level is an indication to this stage there is no credible threat that's been identified prior to the event of this afternoon in boston .

>> and commissioner, if you were back here, would it be your guess that they will have one, two, three assorted views of the suspect on surveillance video by the time we go to bed u.s. time tonight?

>> my sense is that what's happening at this moment there is they are attempting to, one, interview as many of those people who were transported to hospitals with injuries. they are trying to basically certainly be identifying and trying to interview all of the public safety personnel who were assigned to that specific area. they will be attempting to locate and interview people who were in the immediate area who were not injured but who may have seen things going on. they will certainly be looking at whatever cameras are in that area. that area has a bank on the corner with a number of businesses. so the common practice now is to try to identify what cameras are in that area and to retrieve whatever film they may have. the irony here is two hours before this event that would have been one of the most heavily photographed areas in the world because there were hundreds of cameras from all over the world to record the finish of the marathon. this event occurred almost two hours after the first runner and female runner came across the finish line . so it was fortunate in some respects that the device went off two hours after the end of the race, if you will, the front runner . otherwise it would have been much larger crowds in the area at that time.

>> i talked to a woman who said she was in a restaurant just out of the blast zone. they came in. boston p.d. said everyone with a cell phone put it down. was that because they were worried about an accidental ignition of a bomb? was that because they were fearful that maybe someone who was setting off the devices was in the restaurant?

>> you know, brian, i'm going to have to process ignorance about that set of instructions. whether the concern was by the police officers acting on their own that a device oh might have been remotely set off with a cell phone or if there was a concern that cell phone usage might accidentally set off a other as yet unexploded devices. you had a report earlier that as many as five items had been destroyed by the police as a note of caution. they might have contained explosive devices . that particular instruction. i can't help you out on what might have prompted that.

>> commissioner bill bratton , thank you very much for being with us from our london bureau .
