That last I have to believe is to prevent us from effectively defending ourselves from the state. They know we can only send so many bullets, no matter how well armed we are. Booby traps give us better odds to fight or flee from them, should they decide they have a reason to come after us.

That said I can get a permit for blasting if I, in my very rural area, were to find a “legitimate” need to do so. TNT isn’t quite unobtainium, but not easy to get, so it should also be within my rights to fashion my own explosives if I possess the knowledge, skills and tools.

And yeah, tannerite. I don’t have any, but academy sports does. It’s not even expensive, all things considered.
