Reddit reviews Self-Defense by Judo

Nice article. Judo and law enforcement share quite a bit of history.

There are many police-dojos of course. But beyond that, there's even an old judo kata that was specifically tailored for the purposes of law enforcement, the torite no kata:

As you can see, it's full of arresting techniques, renkoho waza. There are entire technical selections for the police. Take this book for example:

> This book is based on the kime-no-kata of the Kodokan and the specialized kime waza of the marunouchi police dojo in Tokyo.

Judoinfo.com also has a few pages dedicated to this topic:

Kodokan teachers were also involved in this:

A minor nitpick, I don't like this part of the article:

> Kano eliminated the destructive jiu-jitsu techniques that would permanently maim training partners.

Kano did not accept inefficient techniques to be integrated into judo.
Judo techniques were either just added the way they were, improved, newly invented and some were modified with the purpose of training safety. But nonetheless, judo techniques can be terribly dangerous, that includes those allowed in randori (throws, chokes, pins and arm locks), but also those that are still part of judo but not allowed in randori (strikes, kicks, leg locks, neck cranks, small joint locks ...).

In short: Kano didn't make the techniques safer, nor did he remove the dangerous ones, he made the way they were practiced safer.

EDIT: Made it a bit more readable.
