One month after a jury acquitted George Zimmerman in the shooting death of Trayvon Martin, the Coalition to Stop Gun Violence has released a new ad that uses a dramatic reenactment of Martin's death to call for an end to so-called "stand your ground" laws.

The ad overlays actual 911 calls from Zimmerman and a witness in re-imagining the incident, which took place in Florida. As the video ends, "Martin" is shown lying prone, dead on the ground, along with other bodies intended to represent victims of gun violence in other states with similar laws.

Zimmerman admitted to fatally shooting Martin, an unarmed black teen, but many said he was justified in doing so because of Florida's "Stand Your Ground" law, which allows for the broad use of lethal force in self-defense.

"We hope our 'Stand Your Ground' PSA will mobilize new activism on the issue and bring us to a point where our laws are acting to protect victims, as opposed to creating new ones," the group said in a statement.

CSGV also launched a companion website and petition calling for an end to stand your ground laws.
