If they act in such a way that they must continue to act the same way to prevent knowledge from being transferred then I could see the courts ruling they must continue to act in such a way even if it would involve lying. The only ways around this is for the information that a warrant was received to be sent before it is received (to give an example that doesn't violate causality, a person stream 100% of everything they see/hear, so that between the time of receiving such a warrant and realizing what the warrant actually is the information that it has been received was already sent out). And even then I see the courts ruling against them because the courts will argue the spirit of the law was violated.
