This is the type of senseless crime

teddyR This criminal obviously wasn't dissuaded by DC's strict gun control laws and ban on public carry.

As if it would've done him any good. You've been watching too many rambo movies. A 68 yr old man isn't as able as a 24 yo young creep like that to snap fire a gun. Are you sure the 68 yo *didn't* have a gun? in glove compartment? rifle in trunk? what good would it have done?
Flash, gun owners carrying concealed get shot & killed too, esp when somebody intent on it gets the drop on them.
Perhaps the DC handgun ban would've prevented this murder, you never know.

teddyr: A majority of these types of crimes are committed by people who either are convicted felons that should not have a gun or purchased their gun illegally.

Toss in felon recidivists who've had their alleged gun rights restored, or passive criminals who haven't been detected as such, still importuning the sacred 2ndA cow.
