Right, in commuting a crime or under suspicion of a crime, certain rights are lost. Think if police showed up to a call of shots fired somewhere, and they saw someone who fit the description, they'd just politely walk up and ask them nicely if they did anything wrong? In this case, he was under the belief she had broken a law and she was being dealt with like a criminal. Later, the facts came out that she was right and no actual crime committed. The investigation will likely show that the police officer was acting within reason .
