I agree that the Donut Shop comments are probably not an accurate stereotype and I also agree that they spend too much on the non-essentials you cited. However, the real reason it's open season on law enforcement is because many citizens are tired of law enforcement excelling at intimidation and generating revenue (speed traps, event enforcement, parking fines, etc.). They are very poor in critical areas such as neighborhood patrolling to deter crime,  timeliness and follow up of non emergency crimes,  outreach and immersion into the community and being genuinely friendly. We pay these people, we are their employers and yet it seems their focus is to collect money from us for piddly violations.
