Tellner, domestic violence murders are nowhere NEAR as common as "crook on crook" murders. The reason they appear to be more common is that each one gets major coverage.
Talk to any street cop in a big city.
The numbers are being hidden to a large degree because murders in the US are very strictly limited to certain demographics.
An example of how serious the disparity is:
In...damn, either 2002 or 2003, I can't recall offhand which, Vermont had six murders total. Washington DC had 262. Both have a population of about 650,000.
A high percentage of the Vermont murders were probably domestic violence. Possibly all of them. But they're a relative fraction of the number of DC murders, almost all of which were gang related or drug crime related.
Committed by people who will NOT visit a shooting range under any circumstances even if ranges exist locally - ranges that are full of cops and/or "wanna-be cops" such as the range workers or ex-cops who often own ranges or act as rangemasters.
It's that "goblin class" that Cooper is very correctly worried about the most. And he's absolutely correct that if you can fight them at range, they're absolutely pathetic. Hell, they're no good at hand to hand either, for the most part...but they're so damned quick to kill that any weapon means they're lethal as hell.
Good example:
Years ago when he was younger and stupider, my kid brother was invited to an Oakland (California) rap concert by a friend. Sure enough a local gang tried to start a riot - they went around the upper walkway in a pack and were randomly rolling people down the stairs. Extensive metal detectors ensured everybody was disarmed but things were going rodeo regardless. My brother is almost as big as me; the friend he was with was bigger. Along with a couple of security guards they formed a "battle line" at one of the choke-points at that walkway and held off over eight times their number of gangbangers long enough to let their section clear out behind them, then fought a running controlled retreat making sure to back each other up and not let anybody get singled out and stomped to death. It was an amazing thing really that they pulled it off but the opponents were pure vicious animals and cowards to boot and couldn't stand up to even a hastily assembled opposition fighting in a coordinated fashion.
That's the sort of dangerous street thug that commits most US murders. And they can't shoot any better than they can fight in a coordinated fashion.
They'll kill you in a heartbeat though, on a whim, no hesitation, no remorse.
You have to recognize that this level of snake exists before you have any change of standing up to them.
