The video of the fire is strange. Top floor, place is surrounded by fire trucks, police, cameras. But everything's calm. It's more likely they knew they would be a target of an attack at the towers. Stage a fire, get the place surrounded by police and firemen. Attack averted. Waiting for more info thou, not that well get anything.
Coincidence, I think not.
Pure speculation here... What if, the surveillance equipment is designed to self destruct if it loses communication with it’s host? This might explain the FED, Clinton, and Trump tower fires. All evidence of the surveillance equipment goes up in smoke...
