attorney daryl parks. he represents the family of michael brown. we also have cnn legal analyst. tom, i want to start with you. this new dash cam video shows the initial traffic stop between the officer and michael scott. we see scott open that car door and run. this is the second time on video we see him run. i wonder from the police perspective, when a, i don t want to say suspect because we don t know if there s enough information to call him suspect but a person of interest runs from you, what s the protocol? what right are you taught you have to use there in response? clearly, in this case we had someone stopped for a traffic infraction. light was out. brake light was out. just a minor every day traffic infraction. the officer comes to find out he s wanted on a bench warrant. he has to arrest him.
