decora writes "Recently the dictator of Belarus, Alexander Lukashenko, accidentally admitted to wiretapping journalist Irina Khalip. Khalip is the wife of Andrei Sannikov, one of the many opposition presidential candidates who was imprisoned after the election in 2010. I am wondering how Lukashenko did this? Can a government tap a modern cellphone system without the company knowing? Or would it require cooperation, like when AT&T and others helped the NSA perform warrantless wiretapping on Americans?"
