The number one defense against crime, though, is to put the hoodlums in jail and let them rot, or better yet, execute them. If you put a criminal in jail for life, you end a lifetime of crime. But you can't do that unless you can catch them. And that is what the cameras are for. Guns are OK if you can carry them and you have the opportunity and ability to use them, but you shouldn't have to meet all those conditions in order to be safe from crime.
Okay, if all those cops and cameras make you safe from crime, what keeps you safe from the cops and the cameras?
