I believe police attitudes changed when they started hiring vets from the first Gulf War that came home with post traumatic stress injuries. I had a friend who came home deeply changed... and he went into policework after... I had no issues with him since were were friends... but the mindset was there... “Us vs. Them”.
I have all the respect in the world for veterans, but I don’t think it’s a good idea for combat veterans to come back and become police officers.
