My question involves criminal law for the state of: California
Ok so here we go, I made a dumb choice and decided to grab some beer on the way out since it was stacked next to the exit at a supermarket, I walked to the corner and a friend picked me up as he drove by in his car, we went back to pick up a friend that was buying things, I was sitting in the backseat not paying attention, the door opened and next thing I know there's a hand on my throat, he dragged me out of the car hitting my head more than once on the interior trying to do so, I had no idea what was going on yet he had not identified himself as security he wouldn't let go of my throat and I started to lose concinous, he wouldnt let go of my neck and I wasn't attacking him in any way, next thing I know I'm face down on the assfault with his foot on me I'm a tall nd skinney guy and this is a big samoan with his partner, also a big samoan. By this time there are bystanders saying they can't do that and are walking up from the parking lot he takes his foot off me and I start to get up I'm kind of lost from getting chocked out, he grabs me and tries to pull me down again and bites me extrmely hard on my back, and I fall to the floor again this time he kneels on me he's easily twice if not three times my size and one of my friends pushes him off, disracted by the growing crowd of bystanders yelling I get up and run away ... I got scraped up pretty bad and like a red mark from his hand on my neck, my head huts from of getting banged around in the car and the ground I have an extrmely bad bite mark on my back, and scrapes and cuts on my head, elbows, and a busted lip, unfortunatly we didn't get any witness names or anything except for 4 people I know that were there... We took pictures of all my injuries after and I've been having a lot of headaches I'm assuming a confusion since I rarley ever get headaches, and a sore throat that makes it hard to swallow or talk, and pain in my neck, I haven't gone to the hospital because I cannot afford it. I was wondering if I would be able to take it to court possibly, but if I take it to court would they charge me with shopplifting ? I currently have a clean record oh and also when I was on the ground the security wich had no uniform, plaincloths repeatedly said " I'm strapped I got a gun in my jeans ill shoot you , ill shoot you" to me and my friends watching. Any help would be appreciated
