In this drill at the SIG SAUER Active Shooter Response Instructor course, a pair of responding officers enter a room with roughly thirty potential targets. Their job: ID and shoot the bad guys without shooting the good guys (or each other). The officer on the left screwed the proverbial pooch; he failed to scan the potential bad guy’s waistline, missed the badge and shot an undercover cop. Imagine the degree of difficulty involved if the crowd was moving and the officers were taking incoming fire. Meanwhile, here’s your takeaway: low ready means low ready. If your gun is too high you can’t scan low. In a situation where a bad shoot will ruin your life forever, you need to check the entire target before unleashing the dogs of war. Something to think about.
