Its both, you broke the law, deal with that part of it, and the cop is a jerk, and you are entitled to deal with that, too. The law needs to be enforced but there is right way and a wrong way. You are entitled to complain about the guy's attitude and threats, and I would.
As for the GC incident: I think about 99 percent of the people in the NPS are great, but there are definitely some aholes among the law enforcement rangers. A couple of years ago in Cape Cod National Seashore, a couple of these geniuses were patrolling a beach in plainclothes, but making themselves pretty obvious. A beachgoer was arrested for warning someone against nude bathing, because the beach was being patrolled. Essentially the same information was posted on a Park Service sign at the entrance to the beach. The guy was charged with "interfering" with law enforcement. Its about getting busts and writing for guys that can't get real cop jobs.
