My question involves an injury that occurred in the state of: California
Here's the situation: I was shopping in a chain/big box retailer—the type that I'm sure has store security at all times. There was a group of four young men being rude and vulgar, yelling, cursing, and generally acting like animals. I heard and/or saw them in at several different points in the store for probably 15 minutes or so. I didn't call them out, nor make any attempt to avoid them; I just went about my business figuring them as annoying but harmless. As it continued, I did get more annoyed, but I still let it slide. While shopping, I took a call from a friend.
Here's where I did something boneheaded: the young men went down the same aisle as me while I was on the phone. I remarked to my friend "hang on a sec, I can't hear you til these loudmouth scumbags move on." At that point, the guys jumped me and gave me a decent smackdown. No lasting injuries or broken bones, but a concussion, plenty of bruises, and shiners enough that I had to stay home from work (it's a customer service job, and the boss didn't want me facing the public). I took a trip to the hospital (no ambulance) and was there eight hours.
The store took an incident report, the police were called, and they got the name of at least one guy because the first thing he did in the store was a return with ID.
Now, I'm wondering if the store should be held liable for this incident. Honestly, if it was a fight over a parking space or a spot in line, that would be a different story, and I'd chalk it up to "stuff happens." But in my view, the store security had plenty of chance to kick these guys out and thus avoid the incident at all. It seems that such an outcome was entirely foreseeable. I'm not looking for some huge jackpot, and while the medical bills are mostly covered by insurance, I missed out on three weeks pay.
What does the law say?
