Israel has long practiced “administrative detention” against , Palestinians, jailing them indefinitely without charge or trial. They call it a lawful preventative security measure using it to target people for political activity, including speech and nonviolent protest.
Even beyond administrative detention, when charges are brought against Palestinians they are almost always tried in military courts that have a near-perfect conviction rate.
Human rights groups have deemed it a violation of international law.
