I always thought that the badge a cop has was more like the shield that Captain America has. It's an obvious sign of good and something you'll protect other people with, but it will also protect you.
I don't know if it matters what country you're from, size of the city you're from, urban or rural, there are people that are hurting each other everywhere.
I like every single actor or actress in the world, because we never know what the conditions are like when they are working. I give everyone the benefit of the doubt and root for them like a psychotic sports fan.
