My question involves labor and employment law for the state of: California
I am 17 years old, male. 3 or so years ago I was caught shoplifting from a local store (a Kmart). Afterwards I was told by the store manager that I was prohibited from entering the premises ever again. I was assigned to do a Juvenile Offender Education class and my charges were erased from my record. However I do not know of any other records that the employer themselves might keep. (Record of the event, surveillance, documented files) or if by completion and certification of the course and expunging of my record, they found no use of the files and disposed of them, or that perhaps maybe store surveillance records are either discarded after a set period of time, or sent to some archive where it would be tedious to have an employer request them as a reference.

Now that I've done a lot of thinking, and my moral compass has been more or less re-calibrated, I am sincerely a different person who has learned a significant lesson in life. One of my good friends has been working there for about a year now and he will put in a good word for me. I plan to apply to Kmart, I am an exemplary student and I've been a member of MENSA.

My question is this, to shorten this up: Would they remember me? Do they keep a reference sheet of the names of shoplifters readily available to compare against the names of applicants?
I don't want to know that for the rest of my life I'm thought of as a bad person as a result of something stupid I did when I was a kid. I am not intentionally attempting to deceive them, my intentions are not malicious. My intentions are to redeem myself because I think that I am capable of doing so given the chance.

They have the right to deny me. I understand that.
I am not asking for your standpoints and abrogations of what you perceive to be my morals in contrast with yours.
Thank you.
