William Melendez was an Inkster police officer a year ago when he stopped Floyd Dent, who was pulled from his car after rolling through a stop sign and punched in the head 16 times.
In a statement a family member read in court Tuesday, 58-year-old Dent said Melendez stopped him because he was a “black man in a Cadillac”.
Melendez told a judge he’s “truly sorry”.
The maximum punishment is 10 years in prison. It is up to the parole board when to release Melendez.
Melendez was fired after WDIV-TV aired the video last March. Inkster agreed to pay 1.4 million dollars (£1m) to Dent.
