Among other things, he writes a weekly column called "The Twilight Zone", in which he wanders around the Palestinian territories and repeats the stories he hears through translators (he doesn't speak Arabic). His trustworthiness is mooted: he claims no-one has ever refuted any of his facts, but there actually have been quite a number of such refutations; in a spat with Ben Dror Yemini last year, Yemini posted a list of alleged untruths Levy had published.
This week's Twilight Zone column told of the IDF checkpoints around Nablus, which have been fully open since 2009, and now are being dismantled. In the days when these checkpoints were operative, however, they saved many lives, including of course Palestinians lives. As recently as October 2008 the soldiers manning the checkpoint apprehended a teenager carrying a bomb. Back in 2004 a number of Palestinian teenagers were apprehended at the checkpoint wearing suicide bombs; one was shot. Here's a CBS report, and here are some YouTube videos:
Notice this isn't the first case, according to the report. Here's the second event of the same month, which ended without anyone getting killed:
So although the checkpoint was never a nice place, and there may have been unfortunate things that happened there, it was put there for a reason, and the reason was justified.
It was always Gideon Levy's right to choose to tell the story only from the perspective of the Palestinians who suffered at the checkpoint, just as it's our right not to take him seriously for doing so. It is however a wee bit strange that this week, when the only event happening at the long-defunct checkpoint is that Israel is dismantling it, he writes an entire column about all the evils the IDF committed there, never mentions the lives saved because of its existence, and also manages not to mention that only new part of the story, which is that it's being dismantled. This does take the art of propagandist writing to a new height.
