Oh one more point I wanna make. Scratching, biting, eye poking are things that people naturally do in street fights with no training at all. You cant label this Krav Maga.
Oh, yeah. Forgot to address this point:
Punching and kicking are also things that people naturally do in street fights with no training at all. Does that mean that people that don't train these things are good at them? Of course not.
In Krav Maga, while you don't train biting and scratching, you do train eye poking and kicking to the groin, as well as other "dirty tactics" such as fish hooks. And just as high level Thai boxers are experts at kicking the legs, high level Kravists are experts at kicking to the groin.
Sort of a funny story: I went to a seminar put on by John Whitman at the headquarters of a large Taekwondo McDojo organization. Now, most of the students that this organization teaches are crappy fighters. This organization is probably where the term "McDojo" came from, actually. The instructors are pretty decent martial artists, though. A few of them are starters in the World Combat League and at least one has extensive MMA experience (he fought Genki Sudo several years ago).
Anyway, Mr. Whitman was asked why Krav Maga emphasized the groin kick, as it was difficult to kick someone in the groin. In answer, he said that he would like to spar the best 5 fighters at the seminar. The head of the McDojo organization selected his best five fighters based on their experience.
Well, the first one came out and threw a couple fancy kicks to gauge the distance. Whitman moved back a few steps and circled away. Then he feinted forward and the Taekwondo fighter immediately tried a spinning backkick. Whitman dropped down low with his hands on the floor in a sort of round sweep motion and kicked the guy straight in the nuts. Needless to say, even though he had groin protection on, that sparring match was over.
So, the next fighter steps up. This one is obviously wise to the situation and keeps his feet closer together. He starts throwing tentative round kicks to the legs with an occasional front kick to the body. Whitman takes the kicks to his front leg, occasionally throwing a jab or straight right into the guy's face. On one particular round kick, Whitman comes forward fast with a blitz of punches. The taekwondo fighter jumps back and throws a high round kick...and gets kicked straight in the nuts. Two up, two down.
Long story short, Mr. Whitman proceeded to kick each of these black belts in the jewels even though each one knew it was coming. The joke that was going around was that Mr. Whitman had ball-seeking feet.
