Mexican gangs are using violence and murder, the same tactics practiced by al-Qaeda and the Taliban to gain influence over the United States. The six groups named in McCaul’s bill are the Arellano Feliz Organization, Los Zetas, the Beltran Leyva Organization, LaFamilia Michoacana, the Sinaloa Cartel, and the Gulf Cartel.
McCaul, a former federal prosecutor and present Chairman of the Homeland Security Subcommittee on Oversight, Investigations and Management, told the committee that the savagery of the drug cartels along the border
... has expanded to include more brutal forms of violence, deaths of civilians and political leaders. ... [I]n March, 2011 a law enforcement bulletin warned that cartels were overheard plotting to kill ICE agents and Texas Rangers guarding the border using AK-47’s by shooting at them from across the border. These are acts of terrorism as defined by federal law.
The shooting of Special Agents Zapata and Avila [Jaime Zapata was killed and Victor Avila injured in an attack on February 15 in Mexico by cartel members] is a game-changer. For the first time in 25 years cartels are now targeting American law enforcement.
