Ok I googled, no police forces came up and only the IDF came up ( as Israeli police officers are ex military they don't count as being taught KM as police) I've worked with many people from many different countries so have a good idea of what they train. However many KM schools claim that it's taught in far more places than it is, it's a 'selling point'. It's USP isn't, and other styles gyms and schools also use 'special forces/police' as their selling point.
Yes, this thread is about KM but you don't seem to understand that there's many variations of it, thought up by various people, as I keep saying it's only as good as the instructor teaching and only as good as the training, just like any other style.
Just no, there is not a style in the world that can disarm a knifeman purely using martial arts techniques without the defender being injured sometimes severely. Anyone who teaches you that you can disarm a knife swinging toward you and you not be hurt is lying. Police officers just about everywhere know this ( and one I can think of is an extremely good martial artist, an MMA fighter, as well as a police unarmed combat trainer).
On the recent terrorist knife attack in London various people took on the attackers, one Spanish man went for them with his skateboard, he was killed. Another, a sports journalist who is also a martial artist also went for them and was stabbed in the throat. A police officer used his baton against one and received bad cuts to both arms, others threw chairs and tables at them. The police shot them dead.
I though many of you would like this though.
