The Broward County, Florida, sheriff's office says it is investigating bodycam video showing a deputy using excessive force on a black man after calling him "boy." The videos shows Deputy James Cady approaching Allen Floyd, who is sitting on the curb of a parking lot holding his 9-month-old son. Cady asks Floyd for his ID. When Floyd asked why, Cady raises his voice and again demands the ID. He then grabs Floyd, with his baby still in his arms, and places him against a car. The incident happened in 2017, but the sheriff's office says it wasn't aware of the video until alerted by the public defender's office recently.
