I had an incident happen to me and a friend just this last Friday night that reminded me that cops are not above abusing their power.

please, now, share with the group. 
I was with a friend I hadn't seen in about 20 years. We went out drinking. I live in town, so we could walk to all the places and weren't driving.
We have a couple pitchers at the bar, and then a pint at another bar. Then we got a couple 6-packs and went down to the duck pond in town and just sat on a bench catching up on old times. 3:00 rolled around, so we neatly placed our empty bottles near the trash can, and started to walk the short distance to my house. With all that beer, needless to say, we were pretty drunk. About a block from my house, I hear my friend say he has to pee. I was wanting to say that we are almost to my house, and that the police station is just over there, but my coordination wasn't quite up to par, and he's peeing before I can say anything. But he was facing a building, and not only was it 3:00 AM and no one was around at that time, but no one would have seen his private parts anyway, because he was right up against a wall. Yes, it was not good to pee right out in public like that, but we were more than a bit drunk, and neither of us were thinking straight.
Sure enough, just as I'm slurring to my friend that there's a police station right over there, a cop pulls up right between me and my friend (he just had finished and was walking to catch up to me). Yes, my friend probably deserved a 'urinating in public' ticket or something (although we really did no harm, in retrospect). But that's not the issue we had with the cop...
The cop pulls up and right from the get-go is a total ass. He was threatening my friend that he could charge him as a sex offender. Yes... a
sex offender for urinating in public. Now I could understand if he had whipped it out in front of a bunch of people and started pissing, but this was at 3:00 AM, with not a soul around except me and the cop, and my friend was hidden by a wall the whole time. That, what I just described, has absolutely
not a damn thing to do with being a sex offender and has
everything to do with just being drunk and having to pee and not making a good decision (because we were drunk).
So, you see, give the cop the
power to charge someone with being a sex offender for urinating in public even though this particular incident had nothing to do with sex and watch the cop start abusing that power.
It turns out that my friend and I were polite as hell, answered every question truthfully with the utmost respect that the cop barked at us, diligently did everything the cop asked, and eventually I think the cop realized that we were not troublemakers but only a couple guys trying to walk home. So he let us go without ever even asking our names or to see our IDs. It also turns out that the cop was full of #$%* about being able to charge my friend as a sex offender for urinating in public. I'm sure the cop thought he could, but I looked it up online, and any decent lawyer would have got that charge dismissed in a heartbeat.
