Who says they were innocent? Perhaps they were terrorists plotting and planning? They were hacked to death with swords by terrorists. "Perhaps" they were terrorists, but "perhaps" you are a terrorist, too. You're certainly defending terrorist murderers (LTTE) and maybe you cheered al-Qa'ida's attacks on the US Embassies in Africa because they killed Muslims.
Terrorism is wrong. Terrorists are evil. Killing innocent people is abhorrent.
What is so hard to understand about that?
There are no innocents. Either you are with us or you are with the terrorists. I know that if I were to be administering justice or fighting terrorists I would use whatever method worked. I certainly wouldn't even think twice about putting underwear on your head. I would be using pig blood in ways that muslims would find abhorrent
