Only a crazy idiot would install crude debilitating explosives in a home firearms display. You could probably share a cell after the neighbor kid gets maimed.
I went back through this thread to see if anyone in fact had recommended planting crude debilitating explosives in a home firearms display. Since I don't see anything that crazy, I'm going to assume that ClapperZapper must have jumped to the conclusion that the Burglar Bomb is an explosive device. It is not. It is an extremely effective extra layer of protection that will make a burglar leave the building post haste, before he can figure out how to defeat locks, safes, etc. It would also make a thief think twice about coming back, and instead seek out an easier target. It was merely a suggestion to Tamid to enhance whatever he finally comes up with.
Just about anything we do to protect our homes and valuables can be defeated. This is especially true if the thief has prior knowledge of what he is up against, be it a safe, alarm system, guard dogs, or one of these Burglar Bombs. And all of them have disadvantages too. In the end, the final layer of security is a good insurance policy.
