(U//LES) Los Angeles Fusion Center: Identifying Mexican Mafia Members and Associates

Humming bird and Marilyn Monroe tattoos may have a nexus to the Mexican Mafia, while “G Shields” (Aztec warrior shields) and mariposas (butterflies) may be decreasing in popularity. As certain tattoos sported by Mexican Mafia members and supporters become mainstream, and because California Department of Corrections is known to use certain tattoos as validation points, Mexican Mafia members may introduce new tattoos to make it difficult for law enforcement and correctional officers to identify membership or affiliation with the group. Tattoos are also increasingly disguised within other tattoos, which can make them more difficult to easily identify.

LAPD Research Paper “Fighting Crime in the Information Age: The Promise of Predictive Policing”

Large police departments maintain dozens of databases. It is unusual to see these computer systems linked together to enable effective analysis. It is even more unlikely that other information sources, such as gunshot detection systems or dispatch systems, are linked into police analytical or fusion centers. Finally, police departments do not link their operations and information systems to other parts of the justice system or social services system. Thus, poor information sharing prevents good analysis and investigation. Even more troubling, poor information sharing can undermine efforts to intervene with individuals or neighborhoods to stop the cycle of violence. The best way to see the future and act appropriately is to have a complete picture of the current situation. Police must integrate their information and activities to enable situational awareness.
