Adam, there's a few problems with your view of dickishness on this.
The cops weren't being dicks to you or anything.

You admit to being drunk in public. Right there, that's illegal. You're allowed to be drunk in a bar, in a restaurant (within reason), or in your/someone elses house. You're not allowed to transition between places while drunk. You are allowed to BE drunk, you just cant let people SEE that you're drunk.
You admit to having an open(ed) bottle of booze. That too, is also illegal. Either because [from their perspective] A) You were drinking it in public or B) You have intent to drink it in public.

If they wanted to be dicks they would have thrown you in the drunk tank for public intoxication. If they REALLY wanted to be dicks, they'd write you the ticket and then also throw you in the tank.
