Re: Is Aikido effective for police?
I have never been taught "one to the head two to the heart" in the military, nor have I ever taught that myself. It is "center of mass". Maybe that is a particular school of thought, or an individual opinion, but not anything I have ever experienced. Head shots are hard to index on the move and not very good targets.
Machine guns are area based weapons, designed to mass firepower. Not that you do not take aimed shots, but they are wider area effects weapons.
In many instances today, Military is dealing with the similiar ROE as civilian police when clearing buildings and rooms. Not that I am an expert by any stretch of the imagination of civilian police tactics or ROE, but we do have to consider "friend and foe" and target discrimination is important.
