In police work recruits are taught to watch the hands when making contact with citizens.
In the first course I took from Paul Howe we were given a scanning hierarchy when dealing with folks we encountered. Guess what the second item on the list is? You got it, the hands.
In the first seminar I attended by Megaton Diaz he made a statement that has stuck with me over 20 years later. “Never let them touch you. If they grab you grab them back.” Megaton was speaking to the importance of never allowing our opponent to establish a grip on us, to always monitor and control the opponents hands.
It seems there is a string that threads through every potentially violent endeavor. The opponent’s hands will hurt you if you don’t control them.
In particular I can’t over emphasize the importance of monitoring the hands of an unknown contact. Your ability to apply your avoidance, deterrence, and deescalation skills are greatly enhanced by your ability to monitor the unknown contacts hands.
Uncontrolled hands for some reason, (looking at you Murphy), seem to migrate to our weapons, don’t let that happen. Control the hands, control the space/distance, get to a dominant position, and finish them.
