Re: aikido for police
For those that point out the use of Aikido in police work.
The techniques can be quite effective but how they are trained is vitally important.
My teacher until a couple of years ago was an instructor to the Osaka police but what he taught and more to the point how he taught it differs from the Hombu curriculum. Still the same techniques but where lies the emphasis. Apparently Judo, Kendo, certain styles of Karate and Shodokan Aikido are considered pluses if you wish to joint the department but once in - they have their own way of doing things.
Another thing to consider is that Aikido is really most effective while the distance is being closed. Not exactly useless when you are within grappling distance but I would consider Judo to be the best best for that. One would think that in the range Aikido works best you would still have hold of your firearm.
