Yeah and I have to be a cop to know that a cop that shoots a handcuffed citizen is a bad cop. I have to be a doctor to know that a doctor who amputates the wrong leg is a bad doctor. I have to be a politician to know what a good law is. I have to be a dentist to know how to brush my teeth. I have to be a football player to know what a good player is. etc
No but you have to have good examples to know what a bad one is..
