Video shows police pushing elderly man to the ground

Fifty-seven police officers in Buffalo, New York, have resigned from the force's emergency response team following the suspension of two officers who allegedly pushed a 75-year-old protester to the ground, a source close to the situation said. An investigation is underway in a protest incident Gov. Andrew Cuomo called "wholly unjustified and utterly disgraceful." The man was seriously injured. #CNN #News
