I don't get the whole fiasco being made out of the Israeli censorship. The strange details make the story interesting, but Israel is still no different than the US, Britain, or any other country with an army or spies. They all have some form of censorship in place.
I am personally against censorship, but I would not call Israel out for doing practically the same thing as everyone else. Also, while I feel bad for Ben Zygier-Alon, anyone that becomes a spy knows what they're getting into. Most spies die from murder, whether from their enemy or the country they serve.
