I don't mind this to be an insult, but you are kind of an asshole too. I still love you, but you come across as a major dick at times here. I'm not sure which profession you are a part of, but it would be unfair of me to judge all of your colleagues because you can be an asshole sometimes.
Cops are just people. They are prone to flaws like everyone else is, and there are good people and not so good people in every profession. At the same time, by virtue of their occupation cops are constantly exposed to the worst people in society, people who kill, rape, rob, assault, and lie. They are exposed to trauma and suffering and pure shit, all the time. That wears people down, even the best of people. It is a very difficult job. I work in the other two areas of emergency services and have been worn down by seeing that shit day in and day out, and people love Firefighters and Paramedics. Cops deal with the same shit but also have to deal with a large segment of society hating them at the same time. It is a thankless job but a critical one in order for the rest of us to live in relative safety.
