Oklahoma paid $175,000 to settle claims that its highway patrol used excessive force against Pearl Pearson, who sued after being injured during a 2014 traffic stop when he was unable to communicate or follow verbal directions. He was beaten "to a pulp," his lawyer Derek Burch said.

The man, Tyron Scott McAlpin, who also has cerebral palsy, was repeatedly punched and shocked with a Taser by the police during an arrest in August. The arrest is under investigation.
