The arrest of Ismael 'El Mayo' Zambada, a major drug lord, has triggered a potential treason investigation in Mexico against officials believed to have facilitated his transfer to the U.S. Zambada, alongside Joaquín Guzmán López, the son of 'El Chapo', was apprehended under controversial circumstances, with allegations that Guzmán López kidnapped Zambada to force him onto a plane to the U.S. This has led Mexican prosecutors to explore charges such as illegal flight, kidnapping, and treason, as outlined in Mexican law. Mexico's President is demanding transparency from the U.S. and has indicated that those involved in Zambada's handover could face severe penalties. Notably, the legal definition of treason in Mexico includes abduction for the purpose of handing someone over to foreign authorities, a clause created in response to previous high-profile cases. Zambada's arrest has reignited discussions about the ongoing battle against the Sinaloa cartel's violent legacy.
