The template for such attacks draws from the tactics seen in the 26/11 Mumbai attack in 2008, and continued with the 2013 Westgate Mall attack in Kenya, the January 2015 Charlie Hebdo and Hyper Cacher attacks in Paris and the November 2015 attacks against the Stade de France and Bataclan. These virtual sieges employ swarming tactics, techniques, and procedures (TTPs) to provide a template for urban strife and insecurity. This article provides an overview of terrorist swarming tactics, expanding the aperture to review the use of similar TTPs by criminal gangs in Brazil in the Novo Cagngaço style high intensity robberies and raids. The article will then review the October 2019 Battle of Culiacán or Culiacanazo, where elements of the Cártel de Sinaloa (CDS) employed urban siege TTPs to counter the arrest of cartel leaders by state security forces. The second incident occurred in January 2023 when the CDS again employed swarming TTPs in an unsuccessful attempt to thwart the arrest of Ovidio Guzmán.

Through social network analysis (SNA) of data from Lantia Consultores, a consulting firm in Mexico that specializes in the analysis of public policies, it demonstrates differential alliance structures within Mexico’s bipolar illicit network system. The Cártel de Jalisco Nueva Generación’s (CJNG) alliance structure is top-down and hierarchical, while the Sinaloa Cartel is denser, particularly in the broader Tierra Caliente region. Additionally, our analysis found a sparse overall network with many isolates (groups with no relations to other groups) and disconnected components. Further, we identified organized crime networks that might fill future power vacuums based on their network positions, following state or rival high-value targeting of major cartels. The implications of these findings are discussed, and policy recommendations are provided.

The case study takes place on a border that John Sullivan conceptualizes as a “hyperborder” due to the complexity and high level of both licit and illicit trade. Sullivan explains how this border region has been heavily contested as criminals exploit weak governance. After 9/11 the increase of security at the border led drug trafficking organizations to diversify into internal drug distribution which required control over micro-territories. As the drug war extended cartel’s became interested in control over rural areas and specifically those inhabited by indigenous as they are ideal for the cultivation of drugs and serve as strategic corridors for trafficking illegal commodities. The high levels of competition around this “hyperborder” creates a dangerous situation as both criminal groups...

He is also known by the moniker "El Raton" (The Mouse) and has a heavily armed bodyguard unit protecting him called Las Fuerzas Especiales Ratón (Mouse's Special Forces). Guzmán's arrest triggered a cartel counterattack and widespread violence throughout Culiacán and throughout parts of Sinaloa and neighboring Sonora where the cartel has a presence. Guzmán was transported to Altiplano prison (Centro Federal de Readaptación Social Número 1) in Mexico City pending prosecution.

The cell helped nine inmates escape including the presumed leader of the Pueblos Unidos (United Towns or Villages), José Artemio Maldonado Mejía, Alias "El Michoacano," "El R" or "El Rabias." Maldonado Mejía is an alleged head of the huachicloero (petroleum theft) enterprise known as the Cártel Pueblos Unidos. Numerous media reports mention the use of car bombs or explosives during the operation.

In this commentary, we summarize two papers published by the Baker Institute highlighting key findings and takeaways.
