Official Corruption in Mexico
"To increase transparency and accountability, the Government of Mexico restructured and augmented their Internal Affairs offices through implementing programs/centers in all law enforcement agencies called 'The Center for Evaluation and Control of Trust,' or more commonly known as 'Control de Confianza.' Moreover, new labor laws constrain judges from reinstating police officers fired for corruption. These efforts, combined with leadership changes in the PGR, have had a positive impact; in 2011, over 40 high ranking officials and hundreds more employees were dismissed from service due to allegations of corruption.
"While federal law enforcement standards continue to improve, state and municipal law enforcement officials remain vulnerable to corruption. State and municipal police have been implicated in the press and social media for facilitating the movement of drugs or contraband, as well as impeding federal or military enforcement operations."
