The fact is, I'm a white dude in my mid-30's, I make a tech salary, and I'm afraid of the police, because an officer with a hair up somewhere could ruin my life for a period of time, if not for good.
The fear I think is more along the lines that police can detain you, arrest you and so on. So I just figure, why chance it? I optimize for lowest risk and I view police as an unnecessary risk.
