There is a site called www.freekeene.com that says that the charge against ‘Big Mike” (Tyner?) was assault on a Manchester police officer. This follows the arrest of someone named Brian Manning for possession of pot.
The quality is very poor. One site says that “Brian Manning and “Big Mike” were arrested for smoking in Veteran’s Park” which is difficult from the claims made in this video. They are both described as activists. Whatever the charge, it does appear that the officer tells the man that he can leave and then accused him of “bumping” him. I do not see any bumping or the basis for an assault charge in the video.
Despite the differing accounts, the videotape does show the benefit of such citizen recordings. Boston police have joined other police organizations, particularly in England, in arresting citizens who try to videotape them during confrontations or arrests, here.
