Hold on, she was the victim here. SHe doesn't need to do encryption because at one point thre was this thing called the constitution.
Yes, she was the victim. However, there are ways of making yourself less likely to become a victim. This is what we are talking about.
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.
