Can I just ask, how does one "aggressively walk towards someone"? Is it a certain swagger? Or is it all in a fucking cop's perception?
The penalty for scaring a cop is death. Statistically driving a cab is more dangerous Than being a police officer.
Yes to both. Don't forget that a whole lot of things are communicated through body language. If I walk toward someone very quickly, with my shoulders squared and chest out and a big ol' scowl on my face, most people would not think that I'm going to ask them if they've allowed Jesus into their life. Cops are trained to perceive threats and so they probably tend to see more threats than people who are not trained to respond to dangerous situations. Attribution is a huge cause of conflict and EVERYONE does it ALL THE TIME. But, we can train ourselves to respond in different ways.
