I don't know how to be an orthopedic surgeon. The closest thing I've had to medical training was a first aid and CPR class. What I do know is that if an orthopedic surgeon, upon first seeing an overweight patient complaining of hip pain says "lay off the cheeseburgers and your hip will be fine, you fat slob", that doctor is doing a bad job. Not only is it hostile and rude, it fails to attempt to adequately understand the situation before rushing to judgement.

I do know a little about how to be a police officer. I went to school for it, but decided that wasn't what I want to do with my life. Accusing a complainant of lying right off the bat without any investigation when the complaint is anything more believable than an alien abduction, then having the evidence of your rudeness deleted is not how to be a good cop. I don't think it really takes much training or experience to reach that conclusion.
