I've been looking for an excuse to ressurect these threads.
Unfortunately, I still need to make a decision soon and I'm not sure which tool is most worthy of my efforts.
I don't carry a firearm, it's virtually impossible in my state but I wouldn't anyway. But if I did, I would spend 10 units of time preparing myself mentally, emotionally, spiritually - viscerally- to use a gun against another person for every one unit I spent becoming proficient with the firearm. That's what I learned from that thread. Assessing situations, setting thresholds of peril, conducting yourself after the event vis a vis law enforcement, etc. It was one of the best discussions I've observed in my time here. It made sense to me. Regards!
