In September, a Mexican drug cartel published a letter on the Internet vowing to kill a state governor, or so the rumor went. Was it true? To find the answer, a woman under the moniker "Calindiux," turned not to the media, but to Yahoo! Answers.
Within hours, fellow Internet users had posted not one, but two letters allegedly disseminated by the drug cartels that have been blamed for more than 3,500 deaths across Mexico this year alone.

Tens of thousands of troops were deployed, but successes have been few. Violence continues unabated, especially between rival drug cartels.
