The Coalition to Stop Gun Violence has released a new public service ad re-enacting the night Trayvon Martin was fatally shot.
The ad, entitled "Stand Up to 'Stand Your Ground," also includes the use of 9-1-1 audio from the shooting.

George Zimmerman's brother responded to the ad with this tweet:
"This pic was also part of the trial & so was the inability to retreat while mounted & pummeled."
The "This Pic" portion of the tweet was referring to the bloodied, George Zimmerman photo seen here.
The Coalition to Stop Gun Violence also started a petition calling on lawmakers from different states to oppose Stand Your Ground laws.
