Then why did he run...and why hasn't he turned himself in, if he had nothing to hide?
Ahh yes, the "if you have nothing to hide" business. Maybe his driver's license was expired? Maybe he was in a hurry. Maybe he didn't want to have his money stolen by the kops/"security" screeners. The list is endless. If you have nothing to hide why should you object to (fill in the list of all sorts of intrusive and unconstitutional police state activities). I don't see fleeing as an admission of guilt.
