Every type of Employment has bad apples. It is just a way of life. Doctors, Lawyers, Factory Workers, Postal Workers, doesn't matter what your career is there is always a few bad apples.
But the media loves to high light police and fire fighters when they get caught doing something wrong. Society believes these people should be held at higher standards. Because they are either city, state, or federal employees. There for the media holds them at a higher standard. So when one does something wrong it comes back on the agency that they work for.
I will admit that there are some people out there wearing blue that should not be. But then again there are some doctors that should not be as well. I am sure there are some people that are in the wrong career field.
But please don't start bashing one career over another on here.
