According to Arizona Gov. Jan Brewer, the majority of people crossing the border into Arizona are becoming drug mules. Brewer went as far as to say that the drug cartels are accosting illegal immigrants, effectively "taking control" of immigration.
Brewer´s comments have been scrutinized as being "exaggerated and racist." Professor Oscar Martinez of the University of Arizona believes that Brewer has no data backing up her claims, saying that she is "mouthing off for political reasons."
Despite increased drug violence in Mexico, crime rates of Arizona border towns have not increased for the past decade. Border Patrol and the Immigration and Customs Enforcement agency were unable to provide data to bolster or dismiss Brewer´s claims.
