we've seen a larger presence, so it was a complete shock to, have something like this happen, obviously, you can still see smoke coming from the ground an area where this all happened in the middle of it the park. >> but one of the things that i'm laura, i think that is important for us to mention is that the nypd and the new york city have kinda made it a point to keep this area of functioning normally, as normally as possible. >> they have these coordinates. but they've, they've tried to maintain public access because this is obviously a big in part a central part of lower manhattan down downtown manhattan, with all these chords and city hall is right over there. the federal building is over here. >> so the fact people have access here is frankly something that a lot of us have been concerned about, about how open the axis has been. and for someone like that to be able to get this it's clothes and do something like that. obviously, major concern about the security of this area.
