So, my brother was at a party and he had a couple beers (Yes, he's 21) The cops we're hiding somewhere and my brother was the first person they saw so they put him to the ground to show everyone that they should leave.
They let my brother go so he walked up about 6 houses to his girlfriends house. He kept knocking on the door when the cop saw him and said "Hey! Aren't you that kid that was pulled to the ground?" my brother kept being honest and civil with him when the cop said "You are arrested for public drunk." He was under the legal limit of public intoxication. My brother was recording the whole thing and put it on YouTube.
I'm not giving you guys the link because I've done it before and you guys spammed his channel.
Even if he was drunk, he was on his girlfriends property so they couldn't do anything about it. (I think, correct me if I'm wrong)
tl;dr My brother was arrested because cops thought he was drunk.
