Neighbors described Robertson as a frail, elderly man — his online profile put his age as 74 — who walked with the aid of a hand-carved stick. Though he regularly carried guns, they said he didn’t seem a threat.
Um… anyone who regularly carries around guns is a threat. You know when you carry guns around? When you might need/want to use them. Like when you’re hunting, or when you’re a police officer. If I see someone carrying a gun around, I will assume that they anticipate using it.
