Nobody said they were Hamas, although there were links provided about Hamas using Palestinian workers in Israel to get intel. They are enemy citizens in a time of war, and many of them tried to slip away, breaking the terms of their employment permits. That alone would allow their arrest, by the way.
I don't give a hoot about your repeated claims to have seen things. We discuss what can be discussed here, not allegations raised by yourself.
As for the rest of your nonsense - was any of the killed? and other than claims - was anyone actually tortured, health seriously endangered and so on? There were cases of abuse - acknowledged and under investigation.
You grasping at straws.
