Basically, verbal judo is basically like regular judo where you are using other people's momentum to parry them, but you are not actively attacking/hurting them, you are redirecting or highlighting win/win outcomes
Written by a PHD professor-turned-cop, so it is a more nuanced/educated view on law & order and less MAGA/racist. Lots of it is verbal de-escalation that the author learned by watching some vets on the force... admittedly none of it has permeated the police force as a whole. It is written for everyday people but the author has the perspective that there are a lot of people (cops included) who needlessly ramp up interactions that lead to conflict, but how this can be avoided with more empathy/thoughtful responses.
Some quirky stories in here, including his fukk ups like where he used excessive force for non-compliance. On the flipside, he has stories about de-escalated a man threatening suicide by telling him that electrocution in a bath tub is too painful of a way to go but if he is cool with coming out of the tub, he will help him find another, less painful way to kill himself, another situation where he talks down a man threatening to kill his 'possessed' son, etc. One of my favs so far is a mentor of his walked into the house of an arguing couple and just grabs a newspaper and reads it before placing a call to try and buy a car in the classified section. The couple go from arguing, to mildly interested, to completely bewildered (and no longer fighting).
