I'm worried that all law-abiding Muslims might be ostracised for this barbaric act.

Probably with good reason, Eliza. Trouble is that until Moslem leaders renounce extremism like this and begin to actively excommunicate the perpetrators of violence most people will believe that this type of behavior is condoned by that religion. I am not saying that is a true picture of Moslems but it is what a lot of people will believe. And world leaders will pander to a vocal majority whether they are right or wrong.

Those "law-abiding Muslims" need to ensure that the extremists are caught and brought to justice by working closely with anti-terrorist police and lobbying their leaders to let it be known that there will be no 'heaven' for the jihadists. Is it Moslem or Muslim BTW? - My first introduction to the religion is when my Dad talked about his ancestors, the Cossacks, fighting 'Mohammedans'! Is that no longer PC?

I hope all is OK for you and your husband.
