(NEWSER) – Brandon McKean could scarcely believe the reason a Pontiac, Mich., police officer gave for detaining and questioning him on Thanksgiving afternoon: walking with his hands in his pockets on a freezing day. "There's 10,000 people in Pontiac right now with their hands in their pockets," the 33-year-old tells the officer in a 70-second video of the incident that McKean posted to his Facebook page; the high that day in Pontiac was 33 degrees. The stop was apparently prompted by a call from a worried citizen who had seen McKean walking, and the officer told McKean he had been "making people nervous." Replies McKean, who is black, "By walking by?" Answers the white officer, "Yeah, they said you had your hands in your pockets."
