As the page notes, some of those cases are also very controversial. Particularly the case of Tarek Mehanna, who was convicted of aiding a terrorist organization for translating some of their documents into English. No evidence was offered that he had assisted with their operations; the criminal offense was letting the rest of us know what they are thinking. (Do you feel safer not knowing? I don't.)

Here's the ACLU page on the Mehanna case:

This case did not result in a suicide; it did, however, feature a sentence of over 17 years.
