Do you have any idea how many of those in a "crowded theater" are packing heat and yet with no incidents?
You take one rare instance of a potential accidental firing and you want to condemn the ten of thousands of cops who are in crowded situations all the time with a chambered round?
Get over your hatred for cops. Apparently, you've had a few run-ins with the Law.
Stupidity should be painful. So, take some asprin. You know absolutely nothing about me. I have never had an unpleasant experience with cops. However, I do see a lot of potential problems with this type of 'training'. Stupid people ignore warning signs and have 'accidents'. Smart people realize the hazards, and prevent accidents. There is a major difference.
