Has anyone read A Nation of Cowards, by Jeffrey Snyder?

An often-overlooked tool of self-defense is a very powerful small flashlight. Several manufacturers make small, well-built flashlights which use 2 or 3 three volt camera batteries, which put even the biggest maglight to shame and can easily be carried in a pocket. It's surprising how intimidating a very bright light in someone's face can be. While no substitue for keen awareness, self-confidence, some basic hand-to-hand combat skills, and the mental preparedness and tactical proficiency necessary to shoot somebody with a gun as an absolute last resort for defending your life, a flashlight is a handy tool to have, and it's surprising how many criminals will flee when confronted with something they didn't plan on.
I think the proper attitude to have while posessing a gun for self-defense is to try to think what you would do if you didn't have it with you. How would you avoid a dangerous situation in the first place? You really don't want to deal with the legal consequences of shooting somebody. Even if you are totally justified in shooting somebody out of self-defense, you must realize that every detail leading up to the shooting will be
intensely scrutinzed by prosecutors whose only goal is to win their case against you. The best thing you can do to defend yourself is to do everything you can to make sure you're never in a position where you need to defend yourself. Use your head first, and your gun last.
If you find yourself in a position where you have no choice but to draw a gun, it will benefit you to posess every tool you can to intimidate the attacker into submission rather than shooting him. A loud voice, laser aiming sights and a powerful flashlight might only teach a criminal a temporary lesson in obedience, but they just might save you a huge legal headache and the cost of putting new paint and carpet in your house.
It's really a shame that our current legal system stymies citizens' abilities to defend themselves, because in the long run the best way to eliminate crime is to stop it right when it happens.
