Dash Cam Video Shows DPD Officers Beating Black Man

Another DPD related headline regarding officers and beatings.  DPD is not the only department nationwide that this type of headline is all too often published.  I am beginning to think somewhere in the police training handbook under procedures for "people that run from police" it states "when caught that all officers united and kick, punch and hit with batons the assailant prior to cuffing".  Saying that I fully support the police and the job and risk they take each and everyday but come on,  Are these beating warranted by several officers at once?
