Well maybe now the muslims will neeed security at their mosques like all the synagogues do in britain because of them.
I am still in disbelief that the mosques and Islam centers here have no security. Every synagogue I've ever been to and every JCC and Jewish library has a security system that requires you to at the very least identify yourself before you can enter.
I dont know where you go, but I dont see security or people checking who enters in the shuls I have been to. The only thing is that I see cops go by shuls on Yom Kippur. (Didn't see any cops or anything for the past 2 days).
There is the atlantic ocean in between, so we don't live very near each other.
But i'm sure the situation in america is the same as in britain.
I think maybe it depends how big the shul is. A big shul is more of a target.
