If you were an officer you would understand.
Law enforcement personnel are the only people (not counting the military) who intentionally put themselves in harm's way to protect people we don't even know. (Since I've been on the job, my department has had 36 officers killed in the line of duty, protecting "the average citizen" that we don't
know.) Law enforcement is the only profession where people intentionally try to hurt or kill us.
The average citizen does not have anything to do with putting a criminal behind bars for a lengthy period of time... Or taking an addict away from his dope for a long time...
As a general rule, the average citizen doesn't have his/her life and the live's of their families threatened by every other bad guy they come in contact with. As a matter of fact, the average citizen doesn't even come into contact with bad guys! But if they do, who do they call? Not the plumber, not the car salesman, not the computer tech, they call the police, that's who! Point being that even if it's the average citizen who has his life threatened, the police are still going to get involved.
