I don't think beaten within an inch of your life before using a firearm in self defense is necessarily the case, howsomeever show me an agency policy or a state use of force statute (for events taking place outside your residence) that flat say 'get to shoot some one who is apparently unarmed with no actual physical contact.'
That seems to be the theme of this particular story. As I said earlier, we need to know more, because, I tell you from a justified LE use-of-force perspective, this seems to be approaching clownshoes:
Slaughter asked Valdivia for money and when Valdivia said that he didn't have any, Slaughter walked away spewing expletives, prosecutors said in court on Tuesday. Valdivia, who was promoted last year to a supervisory special agent, told Slaughter to watch his mouth. The FBI agent's response caused Slaughter to turn back around and get into Valdivia's face before two shots were fired, prosecutors said.
As I noted earlier, there seems to be some blanks left unfilled.
Also note, the judge OR'ed him.
Continuing the conversation, if we are advocating shoot on harsh talk, why do I see all these pictures of folks EDC loadout with asps, oc's, clinchpics, etc.?
Lethal force should be used when a person is faced with a force that a reasonable person would believe to be force likely to cause death or great bodily harm.
