Gun Folks - Recreated the Paris Massacre many times and PEOPLE STILL DIED.

They gave the people guns in a reinactment and they were still killed.

Members of the group, “The Truth About Guns,” recreated the Hebdo offices, then took turns playing the role of the “armed civilian” in the scenario.
No matter how the situation played out, though, one thing remained consistent — if the “armed civilian” confronted the attackers, he or she died. The only time the “armed civilian” survived was when the volunteer playing him ran away at the first sound of gunfire.

“He started shooting,” volunteer Linda Cruz said, “and I started shooting, and I died” — that is, she was shot by a paintball in a area that the group designated was a “critical hit.”
Another volunteer, Parks Matthew, said he “still got killed, but did better than I thought I would.”
