Israel claimed he violated release agreement terms. Allegedly he did so by leaving Jerusalem. He's lawlessly detained uncharged. Israeli military law permits convoluted justice.
It permits detaining Palestinians on false charges. It permits secret evidence unavailable to counsel. It permits rearresting released prisoners for any reason or none at all.
It permits incarcerating them until their sentences are completed. It permits doing so on the slightest pretext. It permits piling on more unjustiable charges.
It permits any damn thing Israel wishes. Palestinians haven't a leg to stand on. Rogue states operate that way.
At least 14 other prisoners exchanged for Shalit were rearrested. Israel falsely claims they planned terrorist activities. Israel calls wanting to live free, championing civil and human rights, as well as self-defense terrorism.
Five of those rearrested were sentenced to between 24 and 38 years. They'll rot in Israel's gulag unless released.
Samer and four others are hunger striking longterm for justice. Israel doesn't care if they live or die.
Administrative detentions are imposed lawlessly. Those held may be imprisoned indefinitely without charge. They're denied due process. They're not told why they're held.
