Denver is under a martial law drill. The videos are below. WeAreChange, along with other citizens are shooting the videos. One of the thugs in he choppers dropped a simulated frag grenade, wrapped in a flag, on the rooftop where they were filming.
Some are speculating that this has to do with the upcoming Democratic National Convention.
