Since it's hard to tell what's going on from the OP's limited knowledge (no offense, just meaning you don't know the guy with the Burms) I think your best course of action is to try and ask your mutual friend to see if everything's on the level so to speak, and offer to give advice if he wants it. It could be the guy might be a great keeper but has no idea about the laws, and might just need to be notified that what he's doing isn't legal in the cut-and-dry sense. Whatever he does or doesn't do after that will be on him.
