Actually, not that easy. I have learned the hard way that every person you meet, regardless of age, race, gender, religion, or political leaning might be a threat to your safety. Sounds extreme, but people like to typecast their villains and those that mean you harm don't necessarily follow your script. Remember the old guy in a wheelchair that murdered a guy in Spenard back in the 90s? Just a harmless old geezer, until he got mad and shot the dude over something stupid. Or the woman that had too much to drink and stuck a rifle in a guys chest out in Emmonak. Or the kid that murdered his stepmom on the Hillside? You never know.
