Follow up: police will
not investigate the accident any further; the reasoning is that there were no injuries, and no evidence of drugs or alcohol. Apparently in that scenario they end their investigation, walking away to let the two parties involved and their insurance companies figure out who pays for the damage to the vehicle.
I guess that's the way the law works and they have more important things to do, but it seems a bit odd to me considering this appears to be a hit and run, plus he threatened the other party. Looks like Suh may have dodged a bullet.
