The huge humpback whale whose friendliness precipitated a surreal seven-year — so far — federal hunt for criminality surely did not feel put upon.

Nevertheless, the unhinged U.S. government, with an obsession like that of Melville's Ahab, has crippled Nancy Black's scientific career, cost her more than $100,000 in legal fees — so far — and might sentence her to 20 years in prison. This Kafkaesque burlesque of law enforcement began when someone whistled.

Black, 50, a marine biologist who also captains a whale-watching ship, was with some watchers in Monterey Bay in 2005 when a member of her crew whistled at the humpback that had approached her boat, hoping to entice the whale to linger.
