We have an American myth that the independent dude with gun on his hip can rid the world of bad guys. Now it’s in our cultural DNA. It’s the thematic root of thousands of TV shows, movies, and video games. We export it to great profit. We base our military stance on it.

It’s a myth. Always has been. Never were one man righteous vigilantes roaming the old west. Never were urban private dicks dispensing justice where corrupt cops fail. Superman and Batman don’t exist.

I would suggest that the best protection is to know the people in your community, especially those who are “not like you.” And know what your kids are up to. *Listen* to them when they are angry and depressed.
