There seems to be some confusion. Nobody is antagonistic as its the officers who are confronting the correspondents (Chris, JP, etc). Chris crossed the street and was on a sidewalk between an east and west bound lane of traffic. New Hampshire does not require the use of crosswalks and he was not in a motor vehicle so the other requests to back up or otherwise get out of the street were legally invalid and intended to confuse. There is also no requirement for individuals to carry ID in New Hampshire. He was a pedestrian, and there were no cars nearby. You can be ordered to provide your name under certain circumstances. This is not what was requested and the officer only indicated he had given an order after the arrest thereby nullifying any claim Chris was violating a police order.
Chris who is the CEO of ThinkPenguin, Inc does not yell insults or similar at police. The videos where you are seeing insults and similar are from JP. JP reacts in a militaristic style which can come off badly from a public relations stand point at times with the masses and even cause confusion as to his political affiliations (that is he is not republican, conservative, etc, he is pro-freedom). For example he is not homophobic, but does yell such insults when illegally confronted by police for recording, in part due to his age, background, and upbringing, but he's not actually a bigoted individual, and has friends who are gay- including ones which he works with as part of New England Cop Chasers.
Chris tends to remain silent during interactions with police up to the point where an officer comes to him and begins an interaction. Unless there is no incident that is and its merely a friendly interaction with police (going up to a police car to find out what the officer is up to).
Chris also does not interact with police as a general rule particularly when they are being the aggressor, but remaining silent can be difficult, particularly when you have to inform officers of things like ones rights in order maintain those rights. For example if you do not invoke your right to remain silent they can take that as consent to being questioned. Chris prefers to remain silent or otherwise invoke his right to remain silent. Chris will stand his ground however and ignore illegal orders or requests- which are generally actually just requests implied to be orders. An officer will say things like "I'm going to have to ask to search you". That's not an order. It's a request for your consent to be searched. If you do not object they can take it as you consenting to a search. You can refuse, but they will get angry and start yelling. They do this to intimidate you.
