A cell phone video showing a White police officer in Jacksonville, Florida, striking a Black man in the face during a February traffic stop before officers dragged the driver from his car has sparked outrage online as conflicting accounts of the incident have emerged.

William McNeil, Jr., the 22-year-old Florida man whose violent arrest by Jacksonville sheriff’s deputies was caught in a viral video, addressed the incident publicly for the first time during a press conference on Wednesday morning. McNeil began his brief remarks by thanking those who supported him, then turned to the Feb. 19 incident.
