There's an easier solution, of course. We just make it illegal for anyone to commit a robbery without shouting "Threat!" and standing still. Dunno why nobody thought of that.
sounds like fun. We’re very limited around where I live as far as firearms training facilities go so I have had to improvise. I wish we had some kind of a semi-realistic combat handgun range.
We should just put up signs that say “No Threat Zone”.
Then everyone would be safe forever.
