9/11 "Truthers" are running a digital billboard in Times Square showing building collapse

9/11 "Truthers" have paid for the digital billboard in Times Square and are running an ad today that states "WTC 7 came down in a classic controlled demolition" and then shows the collapse of building 7.
It's the 'Architects & Engineers for 9/11 Truth ' group at rethink911.org who have placed the 15-second video on a massive billboard in time square today of all days. Building 7 conspiracy theorists believe a controlled demolition involving fire or explosives caused the building to collapse, since it wasn't hit by any plane. Building 7 housed several government agencies, including the Emergency Operations Center known as "Giuliani’s Bunker".
CBS owns the billboard space in Times Square and the cost to rent it is $175,000 a month. The 15 second collapse will run on the billboard starting today, and continue until October 5.
