Not that I've had any experience riding in the back... but... :)
So today I'm thankful I'm not a police officer. Last night was interesting, and we didn't encounter anything too horrific, but there was a lot that I found to be sad. Like the lady who told the convenience store clerk that she didn't have to pay for the 44 oz. Thirst Buster because she owned the store and it was perfectly ok. She also told the officers that she couldn't remember her name, and she didn't have a birthdate because she was never born. She was really an angel and therefore already dead. She was saying some really out there things. The officer had to tell her she was hallucinating. She said "I am? I'm hallucinating? Oh..." This lady had been arrested 58! times for trespassing. She was only about 3 years older than me. It's obvious by looking at her that she's had a rough life.
We took a 15 year old kid home who had been caught smashing up someone's car. He is being charged with criminal damage, but they let him go home. He was drunk when we brought him home.
We went to a 911 hang up call in the city housing project. Little kids ran to hide when they saw the police. I think that's just so sad.
I chose to go to one of the worse parts of town, because I'm not familiar with that area, and because I thought it would interesting. It ended up actually being pretty non-eventful. Most of the calls we went to were either taken care of by other officers before we could get there, or we were unable to find anything. We drove around running plates, but didn't even get to pull anybody over.
So yes, when there's a police car behind you, chances are he IS looking for a reason to pull you over :P :)
