Most decapitations in the Muslim world are not swift as we like to imagine...with a sword or macheti...rather the head ,limbs. or whatever is often done with an ordinary pocket knife or similar..literally sawing slowly and with no mercy whatsoever.
The Berg video showed that. Berg was fiendishly beheaded by zealous adherents of Islam, and what famed modern leaders of modern Islam speak against such fiendish murdering hatreds and ethos! They should do so at EVERY chance, until Islam is no longer properly considered a synonym for a sect of murder, hate, envy and jealousy for everything and anyone advanced beyond the stone-age.
