#Trouble video series. Off the to of my head, I think it's episode #Trouble18 about police training.
Particularly, some schmuck named #DaveGrossman, police trainer.
There's also a podcast series by RobertEvans called #BehindTheBastards (I think therr are 2 episodes abt Grossman) and another podcast #BehindThePolice that u might want to checkout
