Mexico blames U.S. for Mexicans committing crimes in Mexico

To clarify,

A coalition of Mexican mayors has asked the United States to stop deporting illegal immigrants who have been convicted of serious crimes in the U.S. to Mexican border cities, saying the deportations are contributing to Mexican border violence.

Meanwhile, President "Mexicans were here before America was an idea" Obama is trying to pitch the notion that there is no "us" and "them", with regards to illegal immigration [sic].

Sorry, Mr. President, but we're not buying this whole one-world idea and, just as a reminder, you swore an oath to uphold and defend the constitution of the United States of America.
