I’m not worried about me identifying the shooter, I’m worried about the police identifying me as the shooter or hostage taker if I somehow shoot the perp but don’t kill them.
Best case scenario, I shoot someone and risk getting shot by the police, worst case scenario I get shot by the perp (and even worse, they use my gun to kill people), and average case scenario, I get out alive without using the gun. I just don’t see a lot of good things coming out of it. My area is incredibly safe, so the chances of needing it are extremely small, the chances of it helping are even smaller, and the chances of my kids finding it are much higher than I’m comfortable with.
If I was commuting through a bad neighborhood, I could see it being useful. I live and work in safe neighborhoods, so it’s not an issue.
