(AP Photo/Eduardo Verdugo) (Newser) – Arizona's tough new immigration law isn't winning friends across the border: Mexican president Felipe Calderón slammed the law in a speech last night, saying it "opens the door to intolerance, hate, discrimination and abuse in law enforcement." And Mexico issued a travel advisory, warning citizens it's no longer safe to go to Arizona because the law's passage shows "an adverse political atmosphere for migrant communities and for all Mexican visitors," the AP reports. After the law takes effect, the foreign ministry noted, foreigners can be detained if they fail to carry immigration documents. "it should be assumed that any Mexican citizen could be bothered and questioned for no other reason at any moment," the alert says. Calderón said trade and political ties with Arizona would be "seriously affected," the Guardian reports. "Nobody can sit around with their arms crossed in the face of decisions that so clearly affect our countrymen," he added.
