MedicinalMan writes "According to an LA Times piece from Thursday, the US government gave money to Mexico for phone/email tapping. The political implications in Mexico involve the historical relationship of the US and Mexico, and loosening of the Mexican constitution. The implications for Americans however involve potentially skirting 4th Amendment issues by using interception of American/Mexican communication as a basis for warrants issued by American courts. The Supreme Court has ruled that the 4th Amendment only applies to people in the U.S. and the NSA currently has the power (both technologically and legally through FISA) to intercept foreign traffic, but that usually involves national security issues, not "common" prosecution of crimes. With small outlays of $3 million, it seems that it will be relatively simple to monitor Americans from the outside without constitutional protection."
