An Arkansas cop who threatened to shoot Black Lives Matter protesters has been arrested for shooting and killing a fellow officer.

Calvin Salyers allegedly told a superior that if any Black Lives Matter protesters came to his house he’d shoot them through the door.  A few days later, when fellow officer Scott Hutton knocked on Salyers’ front door, Salyers discharged his weapon through the door, fatally wounding Hutton.

Salyers had been admonished that firing a weapon at someone without identifying or even seeing them would be a bad thing, so he claims his gun went off accidentally as he transferred the weapon from his right hand to his left, because that’s a thing that happens. Salyers has yet to explain why he thought BLM protesters would come to his house.
