Growing up I didn't have many good role models. I was quickly disabused of the notion that Preachers are good people when it was a preacher who was shown to be molesting people in the back room of a church we went to. When my dad became the preacher it was even more of a nail in that coffin, because I knew he wasn't perfect and we weren't living in a perfect family either.
I've since realized that nothing is perfect and nothing is always one way or another, especially when it comes to humans. There can be good police and bad police. There can be bad politicians and good politicians. It's best to give people the benefit of the doubt and respect everyone at all times regardless.
