–And if not, why not?
First of all, let me stress that I’m asking simply from idle curiosity. But I was wondering the other day about attack dogs; they’re trained specifically to inflict potentially fatal damage to intruders, yet they are legal to own (so long as a sign is posted warning of their presence). But what about other lethal means of discouraging unwanted guests? If I cared to, could I protect my suburban home by constructing a “death gauntlet” of bear traps, concealed pits lined with bamboo stakes, spring-loaded guillotines, etc.? What about a tripwired shotgun in the foyer, or a huge stone sphere poised to crush anyone who touches my X-Men comics? If I hung up signs reading, “No Trespassing: Beware of Minefield,” could I then use claymores to keep those pesky neighbor kids off my lawn?
