The police are not judge and jury. They only do what they're required by law to do. According to the police report, officers who responded to the 911 call from Bryant's mother did not observe any injuries and she did not complain of pain at the time. Then when she came back days later and showed some evidence physical altercation they are required by law to make the arrest, and let the judge and jury sort out guilt and innoncence. The fact that they arrested and charged him speaks to nothing as to whether she initiated violence or whether Dez was just trying to restrain her. So far we've only got one side of the story, and that's hers, and it seems to change by the day.
