I know that years ago most large departments had clubs for Judo, Karate, and Kendo. But I think that things like Silat and Krav Maga are begining to enter into the local LEO and bodyguard training. I`d say that Judo and Aikido are still the most common here.I was really suprised that the weapons training was so limited though. I`ve seen embassy guards and the PM`s security detail carrying long white riot batons, but other than than I wouldn`t see kendo or jodo haveing nearly as much direct application as say arnis.
