So are you saying that if the files had been encrypted, they wouldn't have been confiscated, all of this would not have happened?
What else precautions one should make not to become the victim of one's own government? Is leaving home allowed? Is there a list of approved websites to visit?
You are making the case that the government is a bullying criminal. And while you can and perhaps should avoid getting the attention of a hooligan/bully/criminal, the government is at least in principle there for you. And in my mind this makes the situation completely different. One shouldn't bow to bullies, but having a bullying government is worse.
And yes, of course the files should have been encrypted. I wonder if they would have detained her in that case.
If the files had been encrypted (after transcription, if needed), then this would be a case about overreaching warrants and illegal government actions, not a case about overreaching warrants, illegal government actions, and wrongful terminations, as that last item will undoubtedly be the end result of the intelligence DHS has collected on the whistle-blowers.
You are right in that she shouldn't have to protect herself and her informants from the government, but such is the imperfect world we find ourselves in while we try to dig our way out of it. She failed her informants. She should have known better than to depend on legal principle to protect her informants from the current administration.
