Personally, I am WAY more concerned about the fact that you say he has/had a few venomous snakes as well, but you didn't seem 100% positive he still had them, or even that you knew more than that he at some point in time had been in possession of them. It's a LOT more dangerous if those little puppies end up getting out and into a neighbors' garage, or have an unfortunate run-in with a kid playing outside and sees the "pretty snake". I know that sounds really extreme, but from the information we've been given, there's no way to determine whether this guy is a responsible owner or not. Venomous snakes are not second-chance animals, and for all we know he could have anything from a Copperhead to a Taipan. That sounds like a much bigger problem than his Burms.
