Driver Crashes into DC Subway Sandwich Store then tries to run (Dashcam)

Earlier tonight I caught this horrific crash on my dash-cam. Fortuitously no person was killed. I took my passengers to their vacation spot and returned to supply the video to police. The officer in cost mentioned they did not want it and it was simply an accident. Mainly simply blew me off with out even trying on the video. Saying there have been loads of witness accounts of the crash.
