In braying for politicians to take down Mr. Murdoch and News Corp., our media colleagues might also stop to ask about possible precedents. The political mob has been quick to call for a criminal probe into whether News Corp. executives violated the U.S. Foreign Corrupt Practices Act with payments to British security or government officials in return for information used in news stories. Attorney General Eric Holder quickly obliged last week, without so much as a fare-thee-well to the First Amendment.

Bribing police and politicians is not free speech.
