Dekalb County GA (Metro ATL):
Now under review for an extraordinary number of deadly force encounters in the last few months...
Shoot-first/Ask-later tactics now under scrutiny/review/modification.
A 92 y/o Atlanta woman shot to death defending herself when plainclothes police made a "no-knock" entry into her home. She was the only one home -- blown away as she opened fire on the those she honestly believed were home invaders. They were after "drug dealer(s)".
Go figure.
Several personal relationships with police agency chaplains and counselors who are face to face with members of the force(s) on a daily basis.
Hope this helps you understand...
Please note... IMHO....
Have a good day...
In other words....you have no data to back up your assertion that LEOs around the country are increasingly infected with a shoot-first mentality.
