There is a fundamental difference between the military and police work.
The bottom line job of the military is to kill people - that's just a fact.
Police officers are supposed to keep the peace.
So why is a "shoot first and ask questions later" former Ranger a top police trainer in the US today?
And what is the connection between between "trainers" like Lt. Col. David Grossman (200+ talks per year) and the epidemic of unjustified lethal attacks by US cops on civilians - and phenomenon that is occurring in no other country.
Quotes from Grossman's seminars for police:
"We are at war - and you are the front line troops in this war."
"There's only one way out...Don't be afraid of being sued...shoot."
