how the german intelligence agency BND can spy on its own citizens
"Dr Stefan Burbaum, who worked at the BND from 2000 to 2005, said that some Germans were targeted as “office holders”, a legal loophole the spies used to circumvent the law that protects Germans citizens from being spied on by its own intelligence agency.
Normally, the intelligence agencies must overcome high legal hurdles laid out in the so-called “G10 law” to spy on German citizens, including when they live abroad.Otherwise, information regarding German citizens has to be filtered out from any foreign communications intercepted by the BND.
But the German spies argue that a citizen working for a foreign company abroad is only protected in his private life, not in his professional communications, Burbaum told the Bundestag inquiry committee into National Security Agency (NSA) mass spying."The office holder is the legal person," Burbaum said. "It's a small exception. But a German citizen can function as an office holder in a foreign organization."The decisive thing is whether he's communicating as a citizen or as an office holder."
just get a bit legally creative
