On January 31, 2007, tens of thousands of people protested in Mexico City against the
dramatic increase in tortilla prices, from $5.00 to $20.00 in the period of a year. The protesters
demanded price reduction and changes in economic policy (DENIS, 2007; KABC, 2007;
CONTEXT; 2007). President Felipe Calderón faced many similar protests occurring across the
country. (Navarro, 2007)
