Big dog has a post on the joke forum about using a snake to hold people up and rob them. I can add to that. A friend with ties to Norway was telling me the new wave of crime (due to strict gun ownership and storage laws) was to use trained attack dogs to hold the owners at bay while the house is robbed. The dogs are trained to attack anyone who moves. It is considered murder in Norway if you kill someone with a gun in your home, even if it is in self defense. This is due to the fact the gun and ammo have to be stored and locked separately. Since you would not have time unlock both and assemble while the guy is breaking in and attacking you, it is reasoned that you were breaking the law to begin with and are guilty of murder. Bull isn't it.
