My question involves criminal law for the state of: Pennsylvania

Earlier today I was caught with a package of white t-shirts. I gave it to the LP guys and went to the office. The police were there but for another situation that arose. The officer searched my bag, ran my ID, and that was that. I signed a couple papers from the LP guys and was told I'm banned from Walmart and Sam's Club. If I return then they'll charge me with trespassing. I fully accept and acknowledge that. They took my photo and that was it. The strange part and this is what confuses me, the police did not issue any kind of citation, did not put me in handcuffs, nothing. Just asked a few questions, carried on a chat and then left to deal with the other situation.

Now I realize that Walmart can press charges, but is the most likely situation I'll just have to pay for damages? As I said, the cops were there but all they did was run my ID and I do have a clean record, plus I'm a military vet(save me the honor lecture) and they did nothing else.

I do feel remorse for what I did and I have learned my lesson.
