Dropbear is correct in saying that there was a super-quick Krav instructorship handed out. There is a really large gap between quality Krav instructors and people who just want to advertise Krav at their dojos. It reminds me of when the Gracies became popular in the 90s. Soon after the UFC tons of dojos began advertising Jiu Jitsu. A TKD place across the street began teaching bjj a couple months after the instructor began training himself. His reason was that he would always be a few weeks ahead of the students. Krav, by nature, should be easy to master but unfortunately it can also create bad Krav. It kind of makes me think of when the term "kickboxing" meant actually something. Nowadays when someone says that they take kickboxing, it could be cardio karate or they train with a guy at a gym that has been kickboxing for only a year...or maybe never actually kickboxed but "hits the bag a lot." Krav Maga is starting to become a generic term, just like Karate. KMWW and IKMA have been speaking out about that for years. If someone gets certified from the big four (IKMA, KMWW, IKMF, KMG...Sorry if I'm leaving one out) it should be good Krav.
Yeah, for a while we'd get e-mails semi-regularly advertising different Krav instructor training programs. Some of them, you didn't even need to have ever taken Krav. Anybody with some number of years of experience in any martial art could go take their $1,000 weekend training camp and come out a certified Krav instructor in their association.
