> can the US government legally issue a National Security Letter to an individual employee that forces them to comply and spy for them? I don’t have a link I can share at the moment to prove this (I’ll update this comment if I find one), but at least in the case of an employee with a security clearance, it is my understanding they can be forced to comply with a US Government order without the ability to inform anyone at their employer (including corporate legal staff). I’m not clear if this order would have to come as an NSL or via another channel.
