CATS, I don't know if you read the full article, the one that was linked from the BWW one to the Daily News one. But, in any event, they were not only arrested but charged with not paying the fare and resisting arrest. Hell, the only thing that was even sort of semi wrong was that when the guy was reaching into his pockets he wasn't clear with what he was taking out. He should have said what he was taking out only because that way the cops would know he wasn't reaching fora gun or anything like that.
I've been in situations with cabbies where they were clearly in the wrong. Not that any cops got involved but still. I was in Queens the past new years, celebrating it with my brother and high school and college friends of his. When a couple of us were getting in a cab to take us to the nearby Long Island Railroad station, I discovered during the ride that the cop was riding with the meter off. When it was time to pay my half of what should have been a ten dollar fare (bumped up to close to thirty) I refused. There was a cop nearby and the cabbie threatened to call him over. And, I kindly mentioned to him that he had no proof of what the fare was because the meter was off, and that what he was doing was illegal.
In any event, it may have been that the actor with Christina just wanted to be on their merry way, but to be arrested after paying double what they should've is nuts.
