Was watching a video called “never get busted” done by a former DEA/former cop who wants to decriminalize weed (not really my fight but I was interested in the LE angle so I watched). He said that most cops arent in their line of work to “serve justice” but rather to keep getting that adrenaline rush from fights, car chases, guys who resist arrest, swat no-knock raids/party vans, etc. Has nothing to do with “upholding the law”. Their in it for the RUSH. It is like crack-cocaine.
I had a young local police officer tell me this directly last October, as we were hosting a "neighborhood watch" block party. We had an incident in our neighborhood about a year previous, and he was one of the cops who caught one of the perps who were stealing cars (and hiding out in our neighborhood).
There is no question about it, although we thanked him for a job well done, he told us that the pleasure was all his, that he and the others live for the adrenalin rush, and they would do it again in a heart beat.
