IF, as others have postulated, you had on a Freedom Arms mini revolver, a firearm, in one of their belt buckle holsters, then it would indeed appear that you are in trouble.
You need to get in touch with a good criminal lawyer. NOW.

I'm closing this before it becomes a speculative dog pile. Or worse.
If, however, you were trying to do a little free advertising for whatever that was in the photo... don't.
