If I were younger, I’d enroll in a Krav Maga class immediately!
I love the way the guy in New Orleans did it except, perhaps, he wasn’t rough enough on the perp. I think he was just so surprised by it. Training would help with that. Anyway, the perp was stupid. He had the gun right in the guy’s face, inches from his right hand. And if you watch carefully, that right hand, very slowly begins inching toward the barrel until he was in excellent position, then BOOM, it’s MY gun now, fool!
