My question involves criminal law for the state of: New jersey
Story behind charges:
In December I went to a walmart with a friend of mine who decided to set off a stink bomb and he got caught. The security manager asked who did it and he admitted it was him and that I wasn't involved. He was taken to the back room to sign a paper saying he wouldn't come back to that store while I was told to wait at the service desk. After he signed the papers he was told to leave so I left with him. About 1 month later I went back to the store, he was supposed to wait in the car but came in a few minutes after me. The security guard seen him and called the police having both of us arrested. The police let him go and sent me to county. Since January I've been in and out of the court 7 times for this trial and it's been postponed each time.
Am I guilty in this case, and if so what penalties am I facing? I have no criminal background. And if I'm not can I counter sue for wrongful arrest or anything else?
I appreciate any help you can offer.
