New footage has surfaced appearing to show the moment George Zimmerman "smashed" an iPad that may contain proof he punched his father-in-law during an alleged altercation last week.
The footage was captured on a home security system moments after the alleged altercation at the Florida rental home where George and Shellie Zimmerman had been living.
Shellie told a 911 operator George took a pocket knife to the iPad and then smashed it ... and the video appears to back up the story.
While you can't actually make out a pocket knife in the footage, it's obvious George is finagling with the device ... before he tosses it on the ground.
Shellie recovers the iPad moments later.
After the incident, Shellie turned the iPad over to cops -- and they're confident they can recover any footage that was stored in the device, but acknowledge it was pretty badly damaged.
As we previously reported, Shellie initially told the 911 operator George was threatening the family with a gun ... but she later recanted her story and police say they've seen no evidence George ever had a gun.
