I think he should have pressed charges the guy learned nothing. His wife might have learned a little of who he really is if she did already not know.
A Thief is a thief and should be treated accordinly.
Wonder how much stuff that old man has really stolen over the years????
I doubt this is new behavior from him, and I'm sure his wife knows at least some of his doings. Most likely she believed it was a thing of the past that he promised he had stopped doing.
I'm doubtful anyone learned anything from this encounter and he will keep on keeping on.
