I was sitting in the lobby on the 8th floor of Marriott Marquis last Saturday. The Marquis is 1 of the largest hotels in Manhattan, huge mult-level underground parking lot and an Atrium in the center of the building that is 40+ stories high. It just seems like a building that could be brought down easier then most Manhattan skyscapers.
The Marquis should put up concrete barriers immediately and ban all cars from the lower level. Those Pakis were doing initial surveillance for an attack. Bet on it.
Plus, they were arrested at 5pm. This area is jam-packed with tourists at this time.
