That must have been in the days before written CALEA standards.
In the interim, Public Safety Officers have learned not to inflame a situation by engaging in colleratal disputes with bystanders.
Perhaps I missed it, but none of the Officers gave any warnings to anyone,except possibly toward the end when the Officer objected to the camcorder, which was itself outside his authority since this all occurred on a public street in broad daylight.
As a LE you don’t let anyone, bystander or not take control of the situation and in this case, based on the video, Mr Striped Shirt was trying to do that. Why do you think backup was arriving as Mr. SS continued with his BS. Answer, he was inflaming the situation and MPD was not about to loose control.
The camcorder, in NH use of recording devices of an individual or individuals, in an area where one would expect not to be recorded, is illegal unless permission is given by the subjects being recorded. Walking down the street with 3 of your friends, and someone comes up to you with a CC 5 feet away and begins recording you is a crime, recording a group people at a ball game is not. Based on the video, Mr. SS and the guy carrying gave their permission since they were doing recording. So the cop objects to the CC, not outside his authority to object.
