My twin brother doesn't even skate and yet he suffered the wrath of cop vs. skateboarder. He took a couple friends to an empty parking lot that they often skated in after-hours. The officer that was usually there (and OK with it) was not there. Instead, this douche was. He told my brother's two friends that they couldn't skate and had to leave. My brother never saw the cop, was never skating, and was never told to leave. He was in the car using the laptop the whole time.
His two friends got in the car and told him that they had to leave, which he did. After getting some fast food or something he later decided that he would go back and talk to the officer himself, explaining that they were normally allowed to skate there and that they apologize for any misunderstanding. Because they were told to leave, this made my brother's two friends in the car uncomfortable but he assured them that the officer had never even seen him and that there was nothing wrong with him returning to talk to the officer.
My brother drove the car through the lot looking for the officer, spotted at him, waved, and then realized that the officer was now beckoning him and pointing, commanding that he come there and stop the car (as if that wasn't where he was already heading).
The officer flipped out. Patting him down, threatening to arrest, calling in other officers, demanding that he answer personal questions about his family ("Who's your father?!" - "I've never met him. I don't have a father." - "What?! Were you hatched or somethin'?!"). He eventually told my brother to get in the back of the squad car so he finally talked back saying "Why? You can't arrest me. I haven't done anything." Don't ever tell a cop that he can't arrest you. After that, he threw the cuffs on and had another officer take him. The other officer looked totally confused with a "do you really plan to go through with this power-trip and arrest this guy?" look on his face, but he put my brother in anyway without reading him his rights (probably thought they were just going to let him go after scaring him).
That was just before midnight on his birthday so he spent the first several hours of his birthday in jail (stayed the night). We couldn't get him out until late morning. The charge? Prowling and loitering. Why would a prowler SEEK OUT a cop if he were truly prowling?! How does one loiter in a MOVING car?! We couldn't get his answers to these questions because he didn't show up in court. The case was thrown out. The officer was excused because he was supposedly in the hospital in a full-body cast but we saw him shopping at Wal-Mart the next week.
