The school resource officer (SRO) who shot and killed 17-year-old Austin Wyatt Rollins at Great Mills High School in Maryland on Tuesday has a history of restraint, video from 2016 shows.

The sheriff’s deputy, identified as Blaine Gaskill, can be seen responding to a domestic disturbance call where a homeowner, later determined to have been under the influence and found guilty of first-degree assault and using a firearm in the commission of a crime of violence, pointed a gun in his direction.
