Unless it wasn't him. There are penalities for filing a false police report.
Really....there isn't much anyone can do about this except buy a cheap assed bike no one wants like a 620....
I wasn't implying that you file a False police report, but if you were in there for like 10 min, when you came out there were still witnesses milling about, and assuming you had a photo of the guys plate, then yea report it.
