Allegations that the CIA facilitated or supported a lethal operation against a Sinaloa Cartel operative in México state have triggered strong denials from both governments while exposing rising tension over U.S. counter-cartel pressure, Mexican sovereignty, and the legal limits of intelligence cooperation inside Mexico.
