Meet the New Robot Army
This was published this past spring but only recently came to my attention. If you haven't had a chance to do so pick up Radley Balko's "Rise of the Warrior Cop" which came out about 4 years ago. Pretty intimidating stuff and it's easy too see intimidating examples if you just pull back a bit.
I thought a couple of years ago ago we were going through a period of racial unrest with a # of police shootings I was seeing a good number of police all too willing to start pulling out their new ex-military surplus toys that I thought we were going down a path from which there was no return.
Note: There is a pay wall involved here but I figured there was a few guys that knew how to get past it , I just signed in.
