1) A few years ago I saw that one high Israeli security official told the Kenesset that we have to thank the Creator that 90% of planned terrorist attacks had been stopped. How were they stopped? Because moderate Arabs informed on their fellow Arabs to the Israeli security forces. It’s very much to our advantage to encourage moderate Arabs, even if we don’t agree with them completely. This happens in other places too, as when Muslims informed on fellow Muslims who were planning a chemical explosion on a flight from London.
2) All the arguments that it’s insensitive to hold prayer services so close the point where Muslims did so much damage leave me concerned that the Arabs could similarly claim that it’s insensitive for Jews to daven in Ma’aras HaMachpelah after what Boruch Goldstein did there.
2) It’s not to our advantage to set precedents for restricting religious freedom.
