George Zimmerman to auction the gun he used to kill Trayvon Martin (Update: auction cancelled)

George Zimmerman, acquitted in 2013 of murdering Trayvon Martin, plans to auction the gun he used to kill the unarmed teen. The proceeds will be used to "fight violence against Law Enforcement officers" by black activists, Zimmerman says.

"I am honored and humbled to announce the sale of an American Firearm Icon," he wrote in the description of the gun used to kill the unarmed, black teenager. "The firearm for sale is the firearm that was used to defend my life and end the brutal attack from Trayvon Martin on 2/26/2012."

"He wrote that the proceeds will be used to "fight [Black Lives Matter] violence against Law Enforcement officers" and to "ensure the demise of Angela Correy's persecution career and Hillary Clinton's anti-firearm rhetoric," though he hasn't expounded upon how.

Zimmerman pursued Martin after finding the 17-year-old's presence in his Florida neighborhood "suspicious," then shot him dead during the resulting confrontation. Martin was visiting a family member who lived nearby; Jurors acquitted Zimmerman after finding that the 200lb Zimmerman was "standing his ground" against the boy, who was black. Zimmerman's last effort to court controversy was his sale of a painting of the Confederate battle flag.

Update: The auction was cancelled, without explanation.
