Following the sound of gunshots, a camera pans to show not one corpse, but dozens of hoodie-wearing bodies on the ground to represent the 26 states with "Stand Your Ground" laws in place.
The anti-gun group's website reads, "Now you can provoke a fight, and if losing that fight, kill the person you attacked."
The video has been viewed more than 22,000 times in the last day. Comments have been disabled on YouTube. Facebook commentary has been very mixed, with some people questioning whether the video exploits Martin's death.
