(CNN) - The windmilling fists and stomping feet rain down blows on the 13-year-old boy.
Trapped on the floor between the bus seats, he cries out as he receives fierce punch after vicious kick from the three bigger, older youths.
As the relentless assault unfolds, the driver of the Florida school bus alerts the dispatcher, pleading for aid.
But he doesn't physically step in to help.
The bus driver, at least according to his school's policy, did nothing wrong.
'Get somebody here quick'
The attack took place July 9 in Pinellas County, Florida. But the horrific cell phone video - and the surveillance video - came out only recently.
As the boy is pummeled, the bus driver John Moody yells at the assailants to leave the boy alone.
He also asks dispatchers to send help.
"You gotta get somebody here quick, quick, quick, quick," he says. "They're about to beat this boy to death over here."
"Please get somebody here quick. There's still doing it," he adds. "There's nothing I can do."
Moody, 64, says he was too afraid to step in.
"The three boys just jumped on him and started pounding on him. And I did all can," he told CNN affiliate WFLA. "I was looking. It was like I was in shock. I was petrified."
Not required to intervene
The ferocity of the attack left the 13-year-old with two black eyes and a broken arm.
"There was clearly an opportunity for him to intervene and or check on the welfare of the children or the child in this case and he didn't make any effort to do so," Chief Robert Vincent of Gulfport Police Department told the affiliate.
According to Pinellas County school policy, the bus driver isn't required to intervene, only to call dispatch.
He can step in, if he feels it's safe.
Other counties actually forbid drivers from physically stopping fights.

(CNN) - Kudos to the president - his call for preschool for every 4-year-old, in the State of the Union address, is a bold and visionary idea. It’s what those who understand the power of early education to unlock children’s minds have been urging for years. It’s what I promoted when I served on the 2008 presidential transition team. But - and it’s a very big but - whether universal prekindergarten really makes a difference in children’s lives or turns out to be a false hope depends entirely on the quality of what’s being offered.
The plus-side first: It takes nothing away from the president’s boldness to note that early education, which used to be derided as baby-sitting, now enjoys widespread popularity. Scientists have learned how rapidly the brain develops during the first years and how much those early experiences build a foundation for later learning. “Skill begets skill,” as Nobel Prize-winning economist James Heckman puts it, and studies of marquee prekindergarten programs show its potential for lifelong impact. Economists have calculated that every dollar invested in high-quality preschool returns $7 - a figure that would make Warren Buffett envious - with greater educational achievement, higher earnings, fewer unwanted pregnancies, lower welfare costs, even lower crime rates.
Parents get it. They are voting with their feet by increasingly enrolling their toddlers in preschool. Voters get it, too. Polling done by First Focus, a bipartisan advocacy organization for children, shows that conservatives as well as liberals support early education. The biggest naysayers are the Republicans on Capitol Hill, but as with immigration reform, gun control, marriage equality and raising the minimum wage, they’re on the wrong side of history.
But expanding preschool isn’t enough. The research shows that if it’s going to have an impact, preschool must be good. Quality costs money, though, and lawmakers have often been loath to underwrite it.
