You do realize that any hard object that hits your skull can knock you out, cause brain damage and kill a person, right?
Now, we find out that these 2 border patrol agents were arresting some of the people when they were attacked.
Again, for the idiots here, getting knocked out or dazed by attackers while carrying a sidearm means that you no longer have control over that gun.
Getting your gun taken from you and then used on you is something no LEO wants to happen. So again, for the retards..Lethal force is oftentimes justified when you are being assaulted with objects that can cause injury or death...especially when there are multiple assailants, and especially when you are in the process of detaining some of those assailants.
Again, you may not like it because you either want illegals into the country or you hate cops/feds in general, but that's just tough shit.
