We all know that grappling is very useful in the street fights, but there was always a question whether leg locks are useful or not in a street fight.
Well, they are! When you entangle your opponent’s legs there’s a huge chance of him being too away from you to do any damage. Your opponent’s legs will be straight enough for him to never do any harm to you.
There’s a logic behind some grappling martial arts heavily focused on leg locks. Leglock your opponent as fast as you can, leave him crippled and move on. While it sounds pretty cruel it’s very effective.
