It's amazing how many gun people talk about "sheeple" yet have the same wooly thinking.
The "sheep" says of the potential armed encounter, "That'll never happen to me! If it does, I'll worry about it then! All that matters is that I don't go looking for trouble."
And then someone smart enough to realize that trouble comes to us without us looking for it, smart enough to carry a gun and know how to use it, says of the predictable legal aftermath:
"That'll never happen to me! If it does, I'll worry about it then! All that matters is that the shoot was righteous!"
Same syndrome, just two different levels of the game.
When the street attack comes, you won't have time to go home and get a gun. That's why you carry one now.
When the legal attack almost inevitably follows the street attack, you won't have time to formulate a strategy; it's best to have already prepared yourself with one.
