Once we grab ahold of our subject in that situation, we find a way to grab and drag that person into a ground fight. And the reason is, standing up, two people, if you're six inches taller than me, standing up, that makes a big difference. But once we're on the ground, we're all the same height. Not only that, once we go to the ground, I have four appendages. If I know jiu-jitsu, I have four appendages, four limbs, that I can use to my advantage ... And the person who does not know jiu-jitsu, when they fall to the ground, they only have two limbs. They only have two hands to operate with.
