"When the police make a reasonable request you should follow it."
Why? Telling someone to sit on the ground is not a reasonable request, they are PUBLIC SERVANTS, they serve the public, they are not there to demand people sit on the ground while they power trip. Unless someone is under arrest or being detained then they have no obligation to obey the word of another human being, let alone one there to serve them.
"they were committing a crime. Its called disturbing the peace and trespassing"
I watched the video, the only people disturbing the peace were the gangsters/executioners the USA call police, and how are the trespassing on public land?
