In James Bond movies, hundreds of men with machine guns shoot thousands of bullets at Bond and his girlfriend and every one misses them. Usually Bond defends himself by throwing a handy empty barrel at several of the closest assailants, but when things get a bit hectic, he squeezes off a round from his Walther PPK and, although he is diving and rolling, his bullet finds its mark.
That is the kind of infantile delusion that animates concealed carry advocates. Real life is different.
Not much detail has been released about this robbery and gunfight at a Rhode Island gun shop -- the kind of place, the gun nuts tell us, nobody ever tries to rob. But the event is common enough that we can run through the possible scenarios.
In the one that is most conformable to gun nut delusions, the robbers intended to kill every possible witness, and the shop owner saved himself (unless he dies, which seems possible still) by using his gun and wounding two of the robbers.
Unluckily, there were three robbers and one of them also shot him, and he was later found bleeding by the mail lady.
This is possible, although nowadays with cameras everywhere shooting witnesses is not as productive a strategy as it used to be.
In most robberies (including other robberies of gun shops, videos of which have been linked here at RtO), the robbers do not plan to shoot anybody, instead using their guns to intimidate witnesses into stillness and compliance. I have talked with several people who have been robbed at gunpoint in gun shops, and they all say they did everything they could to show they were complying.
A typical robbery lasts a minute or less, so the advantage is all with the robber or robbers. Surprise plus intimidation is usually enough to prevent resistance.
But one way to change a robber's mind about shooting is to pull a gun on him. In an example a couple of months ago in Houston, the robbers charged in shooting, and the owner shot back, killing one of them.
What happened in Providence is yet unknown. It may have been like the Houston holdup (without the car crashes that may have alerted the pawnbroker to get his gun ready).
More likely, the robbers would have left the Providence man unhurt had he not decided to shoot it out.
There are 300,000,000 guns in America. Maybe sometimes a good man with a gun can defeat a bad man with a gun, but there's nothing to stop the bad man from bringing along his bad friends, like in the scene in "Jurassic Park" when the human hunter is ambushed by the velociraptor's friends..
What happened to the Providence businessman is regrettable. It would be even worse if it happened because (primary cause) bad men have unlimited access to firearms and (secondary cause) the storekeeper bought in to gun nut fantasies.
