It turns out that 21 states now have "stand-your-ground" laws. (According to CNN.)

The Florida law apparently states that you can only shoot *if* the other person was the first aggressor and *if* you believe that your *life* or someone else's is in imminent danger.

It turns out, again according to CNN, that of the 40 cases of "stand-your-ground" shootings in Florida, most or all involved unarmed victims.

In legislative debates on such laws, law enforcement (a conservative bunch, no?) has opposed them while the National Rifle Association has vigorously supported them. Despite its large membership, the NRA functions essentially as the lobby for gun dealers and manufacturers.

The gun-show loophole is big enough to drive a tank through. It's vigorously supported by the NRA.

Since they don't seem to care who buys a gun at a gun show, NRA members who support the loophole must be crime-proof.
