The trial of Genaro García Luna, former Secretary of Public Security under President Felipe Calderón, has unveiled significant testimonies from three former leaders of the Sinaloa Cartel, who claimed that García Luna was the cartel's "best investment". They alleged that through millionaire bribes, the cartel expanded and solidified its power against rivals in the drug trafficking landscape. The testimonies were made during García Luna's trial in New York, where they described how cartel leaders contributed to a collective fund dubbed a 'polla' to ensure García Luna's cooperation and protection.

Óscar Nava Valencia, known as 'El Lobo', alongside other notorious figures, recounted how the idea of 'making a contribution' originated among the cartel's elite as a practical measure to compel leniency and favorable treatment from García Luna. As described by Sergio Villarreal Barragán, alias 'El Grande', significant amounts of money were allegedly funneled to García Luna since his role as the director of the now-defunct Federal Agency of Investigations. This detail underscores the deep-seated culture of corruption that has plagued law enforcement in Mexico, exacerbating the drug war.

The implications of these revelations extend beyond the trial, raising critical questions about systemic corruption in public institutions, particularly within the security framework in Mexico. The testimonies illustrate the intricate web of collusion between government officials and drug traffickers, highlighting a larger issue that includes the challenges of governance, public trust, and the ongoing violence associated with the drug trade in the country. The case continues to attract public and media attention, as it lays bare the dark underbelly of narcotics control and its implications for Mexican society.
