If I read the article correctly it stated that the cops have their vests on with "POLICE" across it. It also stated that they informed the girl that they were police.

On one of the pulled threads, the reporter brought out that whether or not the police were wearing vests is in dispute. One witness claims to have witnessed the shooting, and she insists the cops put on their vests after the shooting. Another witness is insisting that the cops were wearing their vests before they tried to flag the girl down. In absence of a camcorder, there's no way to determine who's telling the truth.
