As soon as the first cop called it in, BAM, there was at least four cops patrolling (trolling ha) the local neighborhood. The firefighters showed up and started treating the girl who was directly across the street. She seemed shook up, but otherwise in good form. The interesting part is that every five to ten minutes another cop car zooms by at top speed, lights, sirens, the works.
As the incident wears down, the police take their statements from the witness. The SFFD ambulance takes the victim away to the local somewhere, and the street quiets back to it's normal grumble.
