When you say a few, how many do you mean? I guess it depends on how flagrantly he disobeys the law. If he has 20 burms in his home and is working on breeding them, I'd most certainly call the cops. But, if it's just 1 or 2 and there's never been a problem with them, I'd leave the guy alone. If he's good with the animals, takes care of them well, keeps them out of trouble and doesn't act stupid with them, I don't see any reason to call the animal cops. If they've never been a problem for him or anyone he knows, why should they be a problem to you? But if you think there is any danger whatsoever to the man, the snakes, or anyone around him, then alert the authorities. That's just my honest opinion.
