So what crime did he commit?
Ties to a known terrorist group. Enough evidence to have him arrested in most civilised nations. The UK has deported muslims for the same reasons
What "enough evidence" specifically since you seem to know this.
Ties to a known terrorist group, as in lawyers with ties to the mafia or gang bangers with ties to the local drug barons. You cant be selective with laws just because one side is Jewish and so does not deserve any legal support.
If he had ties to a terrorist organisation he would have been charged with it. He hasnt, and neither has he been on the 3 other occasions they have locked him up without charge.
He was involved with a youth movement when he was in college but there is no evidence that he is today. This is a corrupt government silencing critics.
I'm wondering if the fact that he's a journalist is a part of it.
RSF concerned about journalist held without charge since November - Reporters Without Borders
How do you stand on the arrest of muslim terrorists caged in Gitmo then ?
