I dont know if the officer had the opportunity to fire more rounds or if he made the decision to fire only once, but if I was in his place and I had the opportunity to fire controlled rounds at this individual I would have fired as many rounds at this creep as I could.
Are you familiar with story of J. Edgar Hoover and the agent who shot the bank robber but failed to kill him?
Supposedly, Hoover, when asked to sign a commendation for the agent who foiled the bank robbery, instead sent him for remedial maeksmanship training since he failed to kill the perpetrator.
Given the track record of this administration putting agents in jail I would say one round may be one to many. Jorge will need to find a Sutton for the northern boarder.
