SANFORD, Fla. -- City Manager Norton Bonaparte and George Zimmerman lawyer Mark O'Mara had some heated moments during Zimmerman's trial. Now that the verdict is in they agree on at least one thing: It's time to move on.

"Last year people were very angry and they came to Sanford to protest because George Zimmerman had not been arrested," Bonaparte said. "Now he has been arrested. He's been through the trial and a jury has found him not guilty. That's the American judicial system and from that we move forward."

This central Florida city of more than 50,000 people drew little national before February 26, 2012 -- the night Latino neighborhood watch volunteer Zimmerman encountered black teen Trayvon Martin on a quiet street in a gated community, some 20 miles northeast of Orlando.

Minutes later, Trayvon, 17, was dead of a gunshot wound. For months, Sanford and Zimmerman were the focus of national protests. The tragedy has brought changes: Bonaparte himself fired former police chief Bill Lee after Lee received a "no confidence" vote from city officials.

During the trial, O'Mara grilled Bonaparte about his decision to play 911 calls from the night of shooting for Trayvon's family in a group setting.

"We thought it was a courtesy to let the family hear it before it was on the news," Bonaparte testified.
