Sgt. T.J. Hooker and Officer Granger in “The Protectors”

Most perpetrators are right-handed, and are not trained. Therefore when they fire at you, their gun will jump slightly to your right... and their bullets tend to pass over your right shoulder. So... before you get into your combat crouch, take a half-step to your left...

Sir!

Granger?

What happens when you run into a left-handed shooter who's been trained?

In that case, Granger, if you don't take a half-step to your right... you'll get a cop's funeral with full honors.
