"I want another chance," Johnson told the judge.
Means, however, sentenced Johnson to the prison term asked for by the prosecutor - way above the four to five years recommended under state sentencing guidelines.
Means said the video of the beating of Charles Distin by Johnson and cousin Nasire Davis, 16, "shocks the people of Philadelphia. It's what makes people leery about going out. It was a cowardly attack by two against one."
The video, played in court, starts with the interior of the pizza shop as Davis confronts Distin, then 53, and suddenly punches him in the face. Johnson is seen pushing his cousin away from the victim and then dragging Distin outside.
There, another camera shows the cousins kicking and beating Distin as his wife, Ivy Bell, 45, tries to stop them and as the couple's then 5-year-old jumps up and down in terror.
Assistant District Attorney Morgan Model Vedejs did not name the child, who is seen being knocked to the ground outside. She said Distin sustained broken ribs and scrapes and bruises, and was hospitalized overnight.
"This man, he's the adult, he should know better," Vedejs told the judge, referring to Johnson.
Defense attorney Shaka Johnson (no relation) argued that there was more to what happened than what the video showed. Johnson said Distin must have triggered the argument with Davis.
"There's something amiss, there's something wrong with his story," Johnson said of the victim.
He said a long sentence for his client was unjust, adding that Davis was sentenced to house arrest after pleading guilty as a juvenile.
Shaquir Johnson's mother, grandmother, and aunt had asked Means to be lenient and promised to help when he got out of prison.
Vedejs, however, said the video showed Davis "sucker-punch" Distin, and then he and his cousin "beat the crap out of this man for no reason."
She said the victim told police that Davis walked up to him and said, "Do you have a problem with me?" and then punched him in the face.
"It's absolutely egregious," Vedejs added. "It wasn't just a little fistfight. This was an all-out beating."
