My question involves criminal law for the state of: New York
Hello, I was caught shoplifting at a flagship store in NY. I stole around $200 worth of items and the guard caught me through the detectors.
To begin, I did buy items from the store (about $70 worth). First, they checked the store bag and the receipt to assure the items that were bought matched. I went through the detectors again and as expected, they went off. They told me to take every item out of my personal bag and lo and behold, I showed the guard the items I've stole.
I waited about 45 minutes as the employees and guards call, what I assumed to be the actual owner of the store (the position is even higher than general manager). He made me signed this paper with my name, address and school I attended. The paper states that I am not allowed to return to the store until death, or the results will be me handed to the cops and land myself in jail. They took my photo and I was asked kindly to leave.
They did not call the cops, so I wasn't handcuffed or dragged out. Nor did I pay any fines, paid for the items I stole and they did not mention anything about a court case (yet). I consider myself lucky in those parts.
I also need to add an important notice; I was caught twice, however, the very first time I was caught, I was let off with a warning, meaning I can still roam around the store but if I'm caught again, the consequences mentioned above will happen.
I am 22 years old and this is my first criminal offense and I do not have any other offenses in my name, not even a speeding or parking ticket. However, I do enjoy my time in the store and would love to return as I promised myself never to commit this act again since I painfully regret committing such a silly act.
My friend told me to file an arraignment, plea "Not guilty" and ask for a Public Defender. My other friend told me "wait until you age another 20 years and the won't even recognized you or the entire staff probably changed", which I prefer not to do because that was simply stupid (and funny). Although, I do plan to wait 3 years so I can file for independent before I can file an arraignment, but I don't know if that's a good idea or not.
I am also unaware if this goes in my criminal record or not. In addition, I'm not sure if this goes into the National Retail Theft Database, since the store is not chain but flagship and I am only banned from the store alone, but if it does, will the division programs take my name off of it? I just want to join a diversion program and perform any required tasks (whether it's community services or anti-shoplifting course) or pay any fines to get this off my name and able to return to the store in peace, which is my main objective. If it doesn't take it off my records, how long will it last? I still plan to do this anyway to be on the safe side.
Thank you for reading and understanding. Feel free to ask any questions if you're concerned about anything.
