The arrest of over 300 people in a series of drug raids across Mexico has been deemed the largest single strike at a Mexican drug cartel operating in the United States, according to Attorney General Eric Holder. Over the past two days, more than 3,000 federal agents and police officers made the arrests in more than a dozen states, says Holder, aiming specifically at the La Familia cartel. According to the attorney general, La Familia is the newest and most violent of Mexico’s five drug cartels. The raids are the latest effort in a long-running anti-drug operation, which has lead to nearly 1,200 arrests over nearly the past four years. Among those arrested was alleged cartel leader Servando Gomez-Martinez, who was indicted by a New York grand jury.
