Violence, crime and national security provide the themes this week on Latin Pulse. First, the program reviews security in Mexico, and discusses the rise of various cartels, especially the Sinaloa Cartel. Another in-depth part of the program deals with the crisis in El Salvador due to the involvement of street gangs in a transportation strike. Both segments discuss how the central governments in these countries do not have the power to stop the criminal groups. The news segment of the program covers the border crisis between Venezuela and Colombia due to unauthorized immigration, violence and the influence of criminal groups.
