The Best Defense Against a Violent, "Unarmed" Bad Guy...

Is a good guy with a gun.

“This large gentleman just pounding on this lady, closed fist you know multiple times and heavy heavy elbows to the face and neck” says Kreag. 

Kreag has a license to carry a concealed handgun and he served in the U.S. Army for eight years. He worked as a private security contractor in Iraq and he’s a firearms instructor. 

“I was yelling commands at him to stop assaulting her, stop assaulting her.”

"He stopped attacking her and she was screaming, yelling for help and very much hysterical” says Kreag.

The man got out of the car but he was still very angry. 

“Then he turned his attention to the fire arm and was saying ‘don’t shoot me, don’t shoot me.’ I said I’m not going to shoot you, just stay still, don’t do anything crazy. The cops will be here any minute.”

The "large gentleman" (Mr Kreag is clearly being too kind) is MacMichael Nwaiwu.

By the way, is this an unfortunate coincidence?

I put "unarmed" in quotes in the title because the word seems to imply that the person is harmless, which is false.  According to the FBI's annual crime report, in 2012, murderers killed 678 Americans using only their hands and feet as weapons.  That same year, murderers killed 322 Americans using rifles - even those scary "assault rifles".  That's less than half.  Obviously, that doesn't mean that hands and feet are more dangerous than rifles, but it does mean that one should always assume that a violent person is capable of killing, even if that person possesses no weapon other than his/her own body.

It's fortunate that Mr Kreag had his gun at the time of the incident.  Without it, Mr Kreag may have chosen to not intervene.  We don't know how much damage Mr Nwaiwu inflicted on his victim, but it's clear that he would've inflicted much more damage had Mr Kreag not intervened.

If Mr Kreag had intervened without a gun, on the other hand, it seems clear that Mr Nwaiwu would have turned his wrath onto Mr Kreag.  We don't know what would've happened then, but real life isn't a Bruce Lee movie.  Good guys sometimes get curb-stomped.  A gun makes that far less likely.

That being said, good guys with their concealed weapons permits must always remember that a gun is no guarantee of safety either.  It's a tool, not a talisman.  And like every tool, it has limitations.
