I don't disagree with you. I once did some work for a deputy who said with a very haunted look in his eyes that if I saw what he saw I'd run for the hills.
But I've seen too much abuse of power to not expose it.
When I first became an EMT, I was on a volunteer squad in a well to do town in New Jersey. The other members of my crew were very smart, very experienced people.
One day, I asked Jane (a nurse) what was the scariest thing I would see when I did this job. I was expecting a story about a flaming car wreck with body parts all around and screaming relatives, etc.
She looked at me and said, "The scariest thing you'll see is how many nuts live in this town."
I didn't think much of that at the time, but over the years, I watched those nuts murder their children, murder their parents and set the house on fire to cover the crime, rape women, beat women, beat men, try to shoot cops, crash cars into cops, and kill themselves.
I don't think I'm cynical, I think I'm realistic.
No matter how pretty those eyes, you never really know what's behind them.
