and boilston street which is a street where people can go back and forth very easily that have a lot of fro dom and access to that area, that was closed by noon. no more pedestrians were allowed on to that street. to the annoyance of some people who were trying to get on from nearby newbury street. like adam state, most people understood this is what it has to be like. so it was very, very tight in terms of where you could walk. that's not the kind of marathon most people in boston are used to. and i done know if that's what is is going to look like next year. it will be interesting to see if they replicate this. but i think the police really feel like this was the way to handle it and most spectators agreed with them. >> maria -- >> adam, go ahead. >> i'm sorry for jumping in. i was going underscore, to have boilston street closed off i believe from the boston public garden to massachusetts avenue, that's a big deal. i was trying to connect with my cameraman earlier this morning. and it took me a good 45 minutes to basically do the equivalent of crossing a street in two minutes. now

those men are these two brothers, jp and paul norton ofstona, massachusetts were standing along boilstoneet in boston last year waiting for a friend to finish the marathon when they heard the first explosion closer to the finish line. >> i thought it was probably a gas explosion like a manhole cover blew up or something. i saw a flame up the side of the building. >> they tried to get away from the crowd by climbing over the barricades but there was not enough time. 12 seconds later another explosion erupted right next to them. >> i looked down and i was -- this whole leg was ripped open. i was on fire. >> i was in shock. i wanted to reach for my leg. my body won't let me. >> medics and ordinary people rushed to help them. they are working on jp here and paul over here snoo moment, both men lost their right legs, bonding the brothers in a brand new way. only a couple of years apart, they were already close. they ate meals together, played basketball every day. >> we don't do some of the stuff we used to do. not yet anyway. we don't go and play basketball but he has a pool table so i will

where the challenges occur where you have so many people clogged into a tight area like you had on boilstontreet in the end there. that's where the challenge concentrate created. they will have family members and spectators all allowed to be there. of course they will but they will do it in a way that allows everyone to stay safe. the earlier package, increased cam presence, but i think what we saw this week in boston, a stranger saw a backpack left on the side of the street. the police took care of it immediately. there will be some awareness for so spectators and runners will have an eye out for something that doesn't look normal. as we say, you see something, say something. i think that will be the case >> do you worry. >> other cities across the nation. >> absolutely. one of the things we work with all the time. when an incident would happen, the average was since weeks long, it would fate into the background. why we pushed so hard. it's why you can't get on a major event in the country. it's something in a free society to have the balance, the law enforcement present. never eliminate r
