It's a really interesting question. Jiu-jitsu unquestionably works in "uncontrolled" environments. I'd wager large money that if more police officers trained in grappling and submission techniques there'd be far fewer shootings.

I don't have specific experience with Krav per se, but the self-defense I learned getting my Karate BB was kravesque. Krav is fine, but I think of it a little like crossfit; it's mostly a marketing thing. In my estimation, krav can be great for self-defense. But anything where you focus on one or two practical defense moves is great for self-defense. Get good at one or two things and drill it 10,000 times.

Not to derail, but the #1 reason cops reach for their weapons is because they fear a suspect has a weapon. Its a split-second, life-or-death choice. No amount of martial arts training will change that.

Yes but BJJ instills confidence in you and your ability to handle a close range encounter.

Not sure grappling is a great idea with a gun on your hip.
