Gibson refused that lawful order and the judge convicted her.
If the the lawful order was to return to her house, and she refused, how is it possible she was in her house when the arrest occurred?
The appellate court will have the last word on just how "lawful" that order was. I know here in Indiana it would get thrown out of Court in a second. There's no basis for ordering a person off their front yard so long as they are not physically obstructing the cop's activities. Can a cop "lawfully" order you to wash his car and then arrest you for resisting if you refuse? Bogus case.
