i talked to larry silverstein, who leased the property six months before the attacks, and he points to tower 7, who he started in 2002 and finished a few years later. he points to it as a sign of success. i asked if he was to blame for the slow progress at the site. here is what he told me. >> a lot of people say, "you are the villains. you are the reason we do not have the freedom tower." what do you say? obviously, if given the opportunity to do what we are good at doing, we will do it. we have got this building designed, financed, least, and accomplished -- leased, and accomplished. it reflects what could still be done here if given the opportunity to do it. >> he is still in a battle with the port authority of new york and new jersey. jon: share with us some of your memories. you were probably the closest reporter down here to be two towers -- the two towers when they were hit. >> it did not feel real. the thing i had to remind myself was to do my job, to shelve my motions and put them somewhere else so i could just document the day as much as possible. v were four blocks north of
