Home safety I dunno I'm European, we used pitchforks ..

I think you told him personal defense, if you asked him about home defense he would automatically tell you to grab a shotgun

Idk about the rest, but I'm pretty sure you're supposed to put 3 of the seashells on your toilet

You are missing a wire. You use the clips to make a trip wire that springs the 9mm at them, then you beat the fuck out of them with the shells. Conch shells are preferred.
