I've been thinking on this a lot because I feel it is indicative of the downward spiral of police training/skills/selection that we have witnessed over the years. I am not pointing fingers at why and how this is happening, merely using it to show the results of that agenda.
The reason why this particular video is so good for my purpose is it shows the abject cowardice, unethical behavior, perjurious report writing and testimony that is endemic in law enforcement these days. All in one video.
I don't know...I tend to think you might be right but also - has it really gotten worse or has the advent of 24/7 news, instant news, self-recording/reporting devices and social media brought what was normally hidden to the forfront? Regardless - I think this is a good thing in that it calls attention to a problem that needs to be addressed. Dogs are shot to readily, and mentally ill people beaten up. Some police departments have a mental health liason who goes out with officers and helps them deal with a psychotic individual without escalating the situation into a violent confrontation.
