I can't see how it is justified. But it is something that keeps happening. I hear about cases like this from time to time. Someone speaks out against the US government and killing a lot of Muslim women, men, and children and get accused of making propaganda videos for the terrorists groups to recruit people.
A friend of mine was in a McDonald's writing an essay on airplane software safety and a police officer asked him to leave. He had paid for a meal and was using the free Wifi. He responded "If I am not allowed to save this document a plane might fall out of the sky." to which he was arrested with a class C felony threaten with intent to terrorize. They kept delaying his trial for over a year and he had to make a plea deal to get out of jail. But he was in a manic state and didn't choose a good choice of words. He meant that he wanted to prevent planes from falling out of the sky with his essay on a document he was writing and felt the airline industry needed better quality software. This was after flight 370 went missing and nobody knew why.
