I just don't see how a criminal would go on a crime spree with a side hammer muzzleloader or how a kid would be able to get in trouble with it if the powder was locked up. Pretty harmless gesture hanging an old front stuffer on the wall. same reasons I would not worry about a hand saw hanging on the wall but I will lock the blade and unplug a modern chop saw if I am not using it. heck if the powder was not secured I would be more worried about kids trying to make a firework with the powder than them trying to shoot the gun... (don't ask me how I know this)
