...but wrapping a believer in pigskin does not prevent them entry to heaven, if that's really their destination.
The reason that these murderers are not going to heaven is because they killed innocent men, women and children. They were engaged in harabah, not jihad.
Wrapping them in pigskin to "prevent" them from entering Heaven implicitly gives credence to the idea that these murderers were engaging in jihad, and had performed an act worthy of admittance to Paradise.
Overall, wrapping the bodies in pigskin is a foolish and counter-productive action, because all it has done is lend "comfort" to the terrorists, by giving weight to their arguments.
And people wonder why the voice of moderate Islam isn't heard? Because the voice of the fringe is amplified !
