Islam a religion of peace! The extremist’s deeds certainly do not reflect that

And it is wrong that people (their whereabouts and home address etc.) can be identified via facebook in this way. Perhaps this unfortunate incident could have been avoided. So should FB accept some responsibility at least for the above tragedy?

BTW why would FB be responsible?
