I turned down a nearby alley in order to head back home, and was half way down it when a creepy-looking car with no lights on squeaked to a stop and blocked off the end of the alley. I froze and looked at it, and that's when the spotlight came on, and I realized it was a cop.
Unfortunately, my thought process went "oh, I must look suspicious. But wait, I don't have any ID. Maybe they didn't see me yet...", so I hopped into a driveway, out of sight of the cop. Oops, bad move. They went full lights-and-siren, and burned rubber down the alley towards me.
I took off running towards my house, zigzagging between houses to break line of sight. When I got back home, I hopped my fence and went in the back door, just because it was the closest entrance.
Double-unfortunately, apparently the cops decided I was a serious threat, and several minutes later I looked out the window to a police car in my own alley, following a cop with a german shepherd. The dog circled my property, and then barked at the fence, so the cops kicked my gate down and searched my back yard. They jiggled the doors and windows, found them locked, and decided to call it a night.
I got up early the next morning to fix my gate, and my parents never found out about it.
