Just couple weeks ago friend of a friend (priest) was attacked in his own home by a thief with a hammer, he ended up as a vegetable (head trauma) and his mother was killed.
Thief got away with less than a hundred dollars as it was poor family, now in jail, awaiting trial on which he may get a very low sentence if they find him insane.

Shit like this happens all the time and you don't have to be a crypto millionaire.

So if you don't already have a gun, buy one. Glock is the best life insurance
