But at rally on Sunday outside the county jail, Williams argued that Walker never should have been arrested in the first place, saying that deputies "lied and falsified a warrant for his arrest". "I'm not driving, and I haven't done anything wrong".
Roderick Walker, 26, remained locked up at the Clayton County Jail on Sunday, two days after video surfaced showing him being held on the ground by two Clayton County sheriff's deputies and being pummeled by one as he cried out "I can't breathe" and as his 5-year-old son sat in a auto screaming, "Daddy". At least two videos captured what ensued from there; watch them here and here, but note that they are graphic and disturbing.
One of the deputies punched him in the left forehead several times. At one point, Walker can be heard saying "I can't breathe..."
The distraught woman can then be heard screaming, "No!"
"I was just hurt because I wasn't there to protect him", Tywauna Walker said.
When the officers, both of whom are White, finally stood up, Walker was unconscious, his face bloodied and swollen as the deputies flipped him over and put his wrists in cuffs. Williams said Walker went unconscious twice. When the deputies get off him, he is bleeding from his nose and appears to have lost consciousness. The deputy reportedly asked Walker to produce his driver's license, although he was a passenger, not the driver.
One video recorded from a wider angle showed a little boy running around and panicking while Walker was being beaten by the police. The deputy who punched the man laid a forearm across his neck.
Another video shot from afar shows a boy inside a vehicle parked next to the scene, yelling, "Daddy!"
A wider shot video of the arrest shows the second deputy punching the man in the midsection multiple times and then in the head, drawing blood.
Walker was being held without bond because he has a felony probation warrant out of Fulton County for cruelty to children, possession of a firearm by a convicted felon and a failure to appear warrant out of Hapeville, the sheriff's office said.
The vehicle was then pulled over for what was described as a tail-light violation, according to Williams.
A police report shows that Walker was booked on two separate counts of obstructing or hindering law enforcement officers and two separate counts of battery.
Williams, the sheriff's office and the Southern States Police Benevolent Association did not respond to requests for comment Sunday.
Referring to those cases, Gerald Griggs of the NAACP in Atlanta said Saturday that he and others are demanding that Walker be released but that they could be mourning his life.
"We have seen this happen [with] George Floyd, we've seen it happen on too many occasions and we are exhausted of it", Williams said.
