After being oddly slow in objecting to the prosecutorial abuses of businesspeople that have resulted in this, this and this (among many others), the Wall Street Journal ($) editorial page finally gets it right in this editorial on the outrageous conduct of the Justice Department in arresting BetOnSports executive David Carruthers while he changed planes in Dallas. Read the entire piece, but the conclusion sums up the outrage well:

. . . BetOnSports and Mr. Carruthers are not charged with dishonest behavior toward their customers. They are being told that a business they believed was legal was a criminal enterprise even if it was being run in the open. That suggests that prosecutors believe they have the right to enforce compliance with even ambiguous U.S. laws on any business, wherever based, solely because some of the people accessing their site happen to be Americans. As a legal theory, this is a stretch. But as an excuse to incarcerate a foreign national just passing through, it smacks of a politically opportunistic prosecution.
