Okay, So I am 20 years old, and on a Friday night went out to a 18 & over club. There is also a bar inside this club. After about an hour there, I decided I wanted to go home, and walked toward the bar door ( which security stands there) and started waving to my friend to come out of the bar to go home. The security guard told me to step back, which i did, and i continued to try and get my friend out of the bar. The security flipped out on my and told me i have to leave because i wasn't following his orders. I said ok. Another security guard grabbed me and started pushing me until i got to the door, then shoved me out and slammed me against a car and called the cops. I have also heard of several incidents where the security have handled people very badly. I got arrested for disorderly conduct, and mip/mic, which the cops did NOT give a PBT test. Is that legal to charge me if they have no proof? I also have bruises all over my arms. What should I do?
