Mostly good.
I had guns drawn on me in downtown Santa Cruz once, in a case of mistaken identity.
To be fair, the dude they were looking was a) a known acquaintance of mine, b) looked very similar (thin, long blonde hair, blue eyes, etc and c) was being sought for armed robbery. I would be surprised if the dude wasn't either dead or in prison.
Also in Santa Cruz, there was a cop by the name of McConnel that used to go around asking some of us if we thought we were tough and, if so, would we like a shot at him, lol, just like the Wild West.
There was a moped cop that used to ride the riverwalk along River St. A bunch of dudes strung up a line of fishing line or piano wire or something between two bridge walls, hoping to decapitate the fucker.
It only knocked him off his scooter, though, and resulted in more scooter cops.
Good times.
Last time I got pulled over, it was early dawn, heading to work, and barely any traffic on I-65. CHP pulled me over for doing 140. Since I am polite and didn't argue, didn't bitch or make excuses, he let me go with not only a warning, but compliments in both choice of car and music. We shot the breeze for a minute, he said slow it down, be safe and have a wonderful day, I said likewise, and that was that.
I've also gotten tickets, but every encounter has been pleasant.
In my experience, how the Man treats you is almost always dependent upon your own attitude.
