Don't waste your time if you want to buy a hand gun
Carrying a weapon is a big responsibility. More than most anything in the world i hate to hand over money to lawyers. I would accept a robbery or minor injury in order not to kill someone. If you make a error in judgement in A District attorney's opinion,it will cost you to defend yourself in court. Also Civil Suits, every gang banger has a Mother and relatives with hungry lawyers that will suit you for your last dime. Defending your family is very different than defending self. I would risk all to defend family but would accept injury to avoid spending every last cent to defend myself in court.
Going into a bad/strange section of town at night is the height of stupidity in my opinion.
Doc !! You sound a little like George Zimmerman before he learned of the real world. Also be aware that what you post on the Internet will be discovered and used against you. What you post will be twisted and framed in a way to put you a negative light to a jury of the victims peers as well as yours.
