Re: aikido for police
There is no magic bullet martial art for police work. Aikido is terrific for law enforcement as it is effective and techniques largely appear benign to the public, unlike some of the other arts. The downside is that aikido takes considerable time to develop proficiency. You might check into Robert Koga's Practical Aikido - a specifically developed course of instruction of law enforcement that is outstanding. The other arts have their place in police work; brazilian jujitsu certainly fits well with the needs of law enforcement officers. After 30 years as a cop, my view is that the best martial art available to you is the weapon between your ears. Using your head will prevent a whole lot of sweating, biting and gouging and keep your uniform clean.
If you run into your old Chief, Eddie Compass, give him my regards. We went to the FBI National Academy together.
Good luck at the LSP Academy.
