Here is the official report of the arresting officer.
Not only did he initially
refuse the officers request that he come outside and identify himself...but once his identity had been established he
followed the officer outside his home and continued shouting and yelling obscenities at him. He was warned...
twice...that if he continued this behavior he would be arrested and charged with disorderly conduct. He chose to continue the behavior, so he was arrested.
The arrest was legal. His behavior met the legal standard for disorderly conduct. He was warned. He chose to break the law. More importantly...he made a decision to be a
victim, and to accuse the officer of racial bias, rather than to obey the law and cooperate with the police in their investigation of a reported felony in progress.
Obama owes the Cambridge PD a public apology for his ignorant statements during the press conference.
