The charges against ex-police officer Derek Chauvin, who knelt on George Floyd's neck as he begged for air, have been elevated to second-degree murder, and the three other officers at the scene are now charged with aiding and abetting. CBSN's Elaine Quijano spoke about the charges with Michele Rayner-Goolsby, the founder and principal attorney of Civil Liberty Law, who also works with Ben Crump Law, the law firm representing Floyd's family.
