My question involves criminal law for the state of: ID
I'm 21 and was caught shoplifting ~$15 worth of makeup from Walmart (I know, very stupid and it scared the hell out of me). I was confronted after I left the store by a man in plainclothes with a badge and a teenage-looking girl. They asked me if I knew why they stopped me and I said yes, and they took me back inside to a small office. There, I gave back the merchandise and the girl asked for my driver's license, which I gave to her, and took my picture. She then asked for my social security number and had me sign a form (I honestly don't remember what the form was about, I was so worried that I didn't bother reading before I signed it). She said that she would call the manager who could call the police and they could take me to jail. I never saw a manager and after a few minutes the girl told me that they weren't going to call the police or press charges because I complied. After about 10 minutes total, she let me go and said that I'm still allowed inside Walmart stores but obviously if I shoplifted again I would be banned and prosecuted. She told me that this would go on Walmart record but not public record. She gave me a paper with a phone number on it to call to pay my fine, which she said will be between $100 and $250. I don't want to take any risks so I plan on calling the number as soon as their office opens on Monday. However, I'm worried because I've read on other forums that people who paid their fines still received requests from Walmart's law firm for more money. I'm also concerned that maybe I shouldn't have given them my full social security number. If anybody has any advice as to how I should proceed and what could happen, and also if I shouldn't have given them my social security number, that would be very helpful. Thanks.
