@revelette2,
I would hope remember how you feel about this if you are ever in the situation of being attacked by someone and you happen to have a weapon of any kind available to you. After using it once or twice and having your assailant continue to come after you, I would hope you then drop your weapon and fight it out hand to hand since using the weapon any more often would just be way too excessive.
Personally, I'm color blind when it comes to being attacked. I'd be firing my weapon until the person either turned tail and kept running away or fell to the ground. If that means 1 shot, great. If it takes 8, well, I'm fine with that also.
Had Mr. Brown simply obeyed the officer as he should have done, Mr. Brown would still be alive today to continue robbing stores to his heart's content until caught and thrown into jail. And that is the simple truth of the matter.
