Protests after video surfaces of Mesa Police punching a man. Three Mesa Police officers and a sergeant are under investigation after surveillance video first surfaced of them punching suspect Robert Johnson. Today the department released bodycam video showing the encounter and officers ordering Johnson to sit down, when he does not comply he's hit repeatedly. A police report states an officer on the video says Johnson's body language indicated he was going to attack them. Thursday evening, protesters gathered outside the Mesa Police Department calling out what they call abusive behavior by law enforcement. Demonstrators maintain the officers involved in the incident lied about it on their reports and no action was taken until a member of the community brought the video to the attention of the chief. The officers involved are on administrative leave.
