Phoenix Police Department agents used unmarked vehicles fitted with Mexican license plates during undercover operations in Arizona earlier this month [1].
The use of foreign government identifiers by U.S. law enforcement without diplomatic notification raises questions about international protocol and the legitimacy of police tactics.
Videos recorded on April 7, 2026 [2], showed at least two vehicles [2] operating on the streets of Phoenix, including at the intersection of Avenue 29 and Indian [3]. The plates on these vehicles originated from the Mexican states of Morelos and Zacatecas [2].
Jorge Mendoza Yescas, the Mexican Consul General in Phoenix, said the Mexican consulate was not informed by the Phoenix Police Department when undercover agents began using the plates [4]. Mendoza Yescas said the change of plates was intended to protect the safety of officers participating in the operations [5].
One day after the videos were recorded, on April 8, 2026 [3], police arrested 35-year-old José Guzmán [3]. The arrest occurred while officers were utilizing the vehicles with Mexican plates [3].
The Phoenix Police Department has not publicly explained the practice to the press. However, a spokesperson for the department said the practice was "inacceptable" [6].
This discrepancy between the consul's safety justification and the police department's own description of the tactic highlights a lack of coordination between the agency and the Mexican government. While the consul noted the safety intent, the department's internal reaction suggests the tactic may have been unauthorized or contrary to standard operating procedure [5, 6].
“The Mexican consulate was not informed by the Phoenix Police Department when undercover agents began using Mexican plates.”
The unauthorized use of foreign license plates by U.S. police can create diplomatic friction and potentially compromise the legal standing of arrests made during such operations. By bypassing the consulate, the Phoenix Police Department risked damaging bilateral relations and creating confusion regarding the identity of officers operating in public spaces.
