rule # 1 after a shooting:
do NOT talk to police or reporters unless/until you’ve talked to your lawyer and said lawyer is WITH you.
otherwise, you make excited and STUPID statements like this that can/will be used in court of law against you.
Years ago I was playing cards with an attorney, and he told us the best advice ever. He said “You have the right to remain silent, and for God’s sake USE IT! 90% of the problems my clients face are caused AFTER they get arrested because they can’t keep their mouths shut long enough for me to get there, and they end up saying stupid things that go on record.”
I have little sympathy for your common variety thug like he represents, but in the case of a shooting assume that they are going to try and prosecute you no matter HOW clear cut the case for self defense was. Give them your ID, tell them you want a lawyer before you answer ANY questions, and then just stand there mute until they get there and take over.
Good advice, but I would add that it is ~really~ hard to do. In the aftermath of a crisis when things suddenly go from frantic to quiet, and you're coming down off an insane adrenaline surge, the urge to talk it out with somebody -anybody- is overpowering. You get the shakes from the adrenaline, and your mind is racing as it tries to make sense of what probably only lasted a few moments. Talking is part of how the brain processes the chaos and make an orderly record of what you've just been through. Again... excellent advice, but it's important to realize that people often just can't shut up, even when they know better.
