Query: Cashing in on Krav Maga popularity done poorly

Apparently, Kapap is an old acronym for Israeli hand-to-hand fightingso the authors of this book use that term to claim what they're offering predates Krav Maga. And then they proceed to offer a few tidbits of combat principles, Brazilian jujitsu and recycled Krav Maga - none of which is apparently related to the original "kapap" - and do a mediocre job of it.Disappointing.Amazon carries much better books on Krav Maga and on Brazilian jujitsu - go to the search bar and look them up rather than spend your money on this one.
