Darlene Talley finally viewed cruiser camera video of the Dec. 5 incident on Wednesday, after weeks of pushing for answers from CMPD.

The video depicts 18-year-old Tanisha Williams, screaming and banging her head against the Plexiglass in the cruiser 17 times after she was arrested on charges of stealing a T-shirt from CitiTrends clothing store.

When the nearby officers stepped away to grab a restraint device, the video shows Williams wrapping a seat belt around her neck three times and slowly choking for several minutes.

"They should have checked on her, ya know, instead the (officers) were walking around the car talking about Christmas," Talley said.

Talley is now calling for those officers to step down, and asking CMPD to change its policy about suspect restraints. CMPD's current policy does not call for suspects in custody to wear a seat belt while a cruiser is parked.

Talley is also upset about CMPD's decision Wednesday to deny Williams' sister, Porsha, an opportunity to see the cruiser camera video of the incident.

When contacted for comment, CMPD officials said Darlene Talley was Williams' legal guardian, and therefore the only person legally allowed to view the video.
