You know, Drew's story about the cell phone does sound a little too convenient. But you know as well as I do that it is also completely irrelevant. He is not charged with any crimes and he doesn't need an alibi. If that were the case, then the police could check phone records for a little more evidence that the story is true (they already have two witnesses.) But they won't do that. Because it is irrelevant. It was legal for him to be in that parking lot, it was legal for him to be a smart a$$, and the cop was clearly abusive during the incident, and possibly criminal in its aftermath.
The sole point I was attempting to make was that the kid did this intentionally with the hope that he could goad the cop into screwing himself. He succeeded.
