There is absolutely nothing in that video that pertains to anyone other than LE(which I'm not) or criminal (which I really try to avoid being).
I really have to question your abilities for analysis and comprehension.
Stick guy is going nuts beating on the doors of a Federal building. ... Along comes a lone cop and tries to apprehend stick guy all by himself.
Yes, that happened. but it is not at all the part that is relevant to the thread.
It ends badly for the guy with the bat or club or whatever it is.
Yes, just barely, and after the guy attacked the police officer with a contact weapon.
...an officer who, at that point, was
defending himself, and it is for that reason alone that he was justified in the use of deadly force.
Does not apply to this video since it's nothing that an armed citizen should do.
The part in which the police officer pursues the criminal does not apply--the citizen is not sworn to enforce the law.
But
once any perp attacks anyone with a weapon , it becomes purely a matter of
self defense. An armed citizen would
most certainly be justified in the use of deadly force at that point.
The fact that the perp was attacking a police officer who had tried to prevent him from committing a crime has by this time become completely irrelevant. The
reason for the violent attack no longer matters at all.
There is no mention at all of what gun was used so it's not even about "big bullets vs small bullets" (the actual topic of the thread)....
It
is , however, about the defender having the ability to fire controlled shots very rapidly. That pertains to recoil, which does relate to the topic of the thread.
...there's no followup that says when the guy with the bat ceased being a viable threat to life and limb.
That is always the case; it might be investigated in forensic analysis, or not. It doesn't matter. The video shows very clearly that the officer had an objective reason to believe, based on what he could know at the time, that his actions were necessary, lawful, and proper.
I'm sorry - all that video shows is a cop backing up and shooting a threat multiple times.
As CDW4ME posted, "substitute a citizen for the officer, ex: citizen being attacked by determined sociopath with impact weapon".
If you have not yet wondered how your "I learned to make every shot count and to conserve ammunition" concept would have worked under a similar attack", you need to think about it.
It's not clear whether you are seriously confused or are being deliberately obtuse.
BUT: I would
strongly recommended that you avail yourself of some good defensive pistol training
and a good course in use of force law.
