Are you scared when you see the cops?

Yep. In my country, it's better to not make eye contact with the cops at all. Thieves. And murderers. The cops in my country are a mafia. Backed up by the municipal authorities. This is why no one chooses forensic sciences as a profession at all. Either you support the mafia, or you die because you're honest. My forensic professors have been through some shit and their families' lives have been in danger frequently. One of my professors even publicly challenged an authority figure to act on his threats, but only in exchange for being exposed in court. He had a lot of evidence on the mafia boss and his little minions aka the cops.
