I will say this...if you are a University/College police department officer, you are probably pretty screwed if a shooting, or hell, any significant use of force occurs no matter how in the right you are due to politics.
Eh, most of the university police back when I was attending knew their primary job was to never under ANY reasonable circumstances admit a crime occurred other than speeding tickets or any other metric that wouldn't make the college crime rankings. They'd refuse to report theft, rape, assault, you name it. But they did and would ticket for 1mph over the speed limit.
A friend of mine was given a DUI for operating a wheelchair while under the influence. That went away only after he threatened an ADA lawsuit.
There was one good to excellent officer that I knew, he switched departments in pretty quickly however. Good departments virtually never make the news. They attract and retain good cops, and because they do a good job, they don't make the news. Bad departments weed out the good officers, directly and indirectly.
