If those agents( state authorized or otherwise) are indeed located in the US, then what you say is correct. When located in a foreign country things aren't quite so cut and dried. This is why cyber security should be paramount, if one really cares about the confidentiality of data and the importance of systems that are computer controlled. However, user convenience usually trumps real security with often disastrous results for those entities that are on the recieving end of a cyber attack (Sony, for example). It's time the US wakes up to the vulnerability of it's cyber infrastructure since there are few countries as dependant on it as it is. 

"That in no way means that we should ignore it when it's done (by anybody).None of it is OK."

Not ignoring it would mean hardening security of sensitive systems, much easier to cast about for scapegoats and continue with business as usual. I guess I missed the mass national protests over US actions, past and present.
