Los Angeles ? Celebrities from hip-hop star Snoop Dogg to motivational speaker Tony Robbins lamented the execution of Stanley Tookie Williams at a funeral Tuesday that drew hundreds to the violence-racked area where Williams founded the murderous Crips gang three decades ago.

Under heavy police presence, mourners including gang members flashing hand signs waited in line to enter the 1,500-seat Bethel AME Church for a ceremony that stretched more than four hours.

After the service, many of those outside the church dropped to the ground after hearing what sounded like three gunshots about a block away, but there were no injuries and no arrests.

Vendors sold T-shirts with Williams’ picture, and a large TV set up in the parking lot allowed the overflow crowd to watch the service. Williams was executed Dec. 13 despite clemency pleas from celebrities and others who said he had rededicated his life to peace.

“It’s nine-fifteen on twelve-thirteen and another black king will be taken from the scene,” Snoop Dogg told mourners, reciting a poem about the execution. The line “I don’t believe Stan did it” drew wild applause in the parking lot.

Williams, 51, was put to death by injection at San Quentin Prison for the 1979 shotgun murders of a 7-Eleven clerk and three motel owners.

“The war within me is over. I battled my demons and I was triumphant,” Williams said in a recording played to mourners, whom he asked to spread a message to loved ones.

“Teach them how to avoid our destructive footsteps. Teach them to strive for higher education. Teach them to promote peace and teach them to focus on rebuilding the neighborhoods that you, others and I helped to destroy.”

The Rev. Jesse Jackson decried the execution of Williams, who Jackson said saw himself in the end as a “healer, not a predator.”

“Tookie is dead. We’re not safer, we’re not more secure, we’re not more humane,” Jackson said.

Robbins told the mourners he knew Williams only a short time but said he had “so much rage and so much anger” after his execution.

While on death row, Williams wrote children’s books warning against gang life. Those efforts attracted supporters who lobbied for clemency, arguing Williams had redeemed himself. But Gov. Arnold Schwarzenegger was unconvinced, and refused to spare his life.

In his will, Williams asked that his remains be cremated and the ashes scattered over South Africa.
