It's a reverse lottery...
In a normal lottery, the odds of winning are small, but if you win, you win BIG. You can have practically everything you ever wanted. Sure, it's almost impossible for you to win against such odds, but someone wins almost every day... And you can't win unless you play.
In a reverse lottery, the odds of losing are small, but if you lose, you lose BIG. Maybe you get to watch your wife or daughter raped. Maybe you get killed. Maybe you are maimed for life. Maybe you lose many posessions and get to deal with the trauma of being attacked or imprisoned in your house. Sure, it's almost impossible that it will happen to you--the odds are dramatically against such an occurrence, but it happens to someone almost every day... And you can lose even if you decide not to play.
I think CCW is a great idea, but not if it makes you see everything as a threat.
Sort of like saying that owning fire extinguishers is great, but only if they don't make you see everything as a potential fire hazard. If that sounds crazy it's because it is!
I know people who refuse to lock their doors. It's because they feel (at some level) that by doing so, they would be admitting that bad things can happen to them. By intentionally leaving their doors unlocked, by not preparing, they are affirming that they are safe--that their neighborhood isn't dangerous--that bad things can't happen to them. They feel better, but they're fooling themselves...
Bad things happen in bad neighborhoods. Bad things happen in good neighborhoods. Bad things happen in the city. Bad things happen in suburbia. Bad things happen in the country.
Odds are that you'll never lose the reverse lottery. But if you do, life will never be the same.
Good luck!

P.S. I'd rather keep luck out of it as much as possible.
