^ (@ TheSpectatingLoner, as a couple more posts came in while I wrote this) Though "only" for a day, you were a political prisoner.
In 1990 I was accosted, and told "You are under arrest for the possession of marijuana." (I had two joints on me.) Things changed, though, as the process moved on. I was in the drunk tank for a couple hours as they figured out what they were doing, after they confiscated all of my money (because their drug dog did a positive "hit" on a bunch of cardboard boxes I was transporting, which can get a little smelly on a deep overcast and humid day) - "obviously" my money was derived by making a big sale or something.
I had some discretion in what I chose to do. This was more than 300 miles from home. I could have fought it in court, and very likely won, but spending a ton of money for a lawyer (probably nearly as much as they seized from me), and making the trip to Court only to find out the prosecution had put in for a continuance. (How many continuances and wasted trips? Three? Five?) No matter what happened, even if acquitted, very likely there would be some trace of it on my record.
At the time I wasn't thinking about the ability to do things such as entering Canada for a visit (which I think is impossible with any kind of CRIMINAL record, no matter how trivial - speeding tickets and such are VIOLATIONS not crimes).
My decision included having to make some assumptions. After they finished their processing, I was free to go, no jail, no court date assigned. "NO COURT DATE? Um...I think this is their PARTYING money, and I don't think there's any official paperwork anywhere, and therefore NO police record."
The "receipt" they gave me for the seized money was ANYTHING BUT official, it was just a small mimeographed or photocopied half-sheet which didn't even fully explain the seizure. That further made me realize that no report of any kind would probably ever be seen outside that small town in Minnesota. I just let it be, confident that doing so would assure that nothing ever showed up, because this was nothing more than a shakedown.
Which, in my case, I consider to be THEIR crime of armed robbery...and I left, thankful that they didn't steal my car as well, etc.
OTHER THAN THAT, NO OTHER ARRESTS EVER.
