oh come on man, you can't be that blonde...the numbers are low but to simply say it has never happened is complete BS
first article that came up on google for ccw + homicide
The paragraph directly following also says:
The Dade County police also recorded the following incidents involving defensive use of licensed concealed firearms: two robbery cases in which the permit holder produced a firearm and the robbers fled; two cases involving permit holders who intervened to attempt to stop a robbery, but the robbers were not apprehended (and no one else was hurt); one robbery victim whose gun was seized by the robber; a man who shot a pit bull that was attacking him; two cases of a citizen capturing a burglar; three cases of a burglar who was frightened off but not captured; one case of thwarted rape; and a bail bondsman who fired two shots at a fleeing bail-jumper wanted for armed robbery. There were no reports of permit holders shooting innocent people by accident.
He was probably thinking of the fact the no one with a class 3 licence (machine guns) has ever committed a crime (except one incident involving a cop who managed to get forged papers approved by the ATF).
