It’s unclear why a mugshot has been taken of former NFL quarterback Donovan McNabb. But a mugshot of McNabb has indeed been taken.

The mugshot also has been released publicly by the Maricopa (Arizona) County Sheriff’s Office, with no explanation of the purpose or reason for the mugshot.

It’s rare for a law enforcement agency to release a mugshot without explaining why the mugshot was taken. But that’s precisely what has occurred.

AZFamily.com, which has posted the mugshot on its website, says that more details are coming. The details, frankly, already should have arrived.
