Youth Suspect in Seattle Police Punching Case Had Prior Criminal Rap Sheet
People are allowed to photograph from a distance but not to interfere with a lawful government activity. Unless you have a matter of safety to mention, like knowledge that someone has a medical condition that would be relevant to the officer or knowledge that they are armed, you should not say anything to the officer while he is focused on making the arrest. If the officer was aware that the person being arrested was a minor then he could I believe order people not to photograph her, to protect her privacy and not his own. The efforts of the person doing the video to distract the officer and dissuade him from carrying out his proper duties were unlawful. The person who who made those comments, "Are you serious" and "You are ripping her clothes" who is I believe the person recording this, should be arrested. We should definitely not throw in the towel.
Actions meet Consequences.
