There will be no prosecutions. The settlers are an arm of Israeli policy to create facts on the ground and to treat all Palestinians like dogs so they will voluntarily leave the W/B. Israel has not yet given up on the dream of Greater Israel; all the land without the non-Jewish people. The settler violence should be seen within the context of Israel's supposed God given right to the land. Pretty hard for Israel to then turn around and even attempt to impose justice.
