It should also be remembered that public beheading is the legal means used for Islamic judicial executions/the death penalty in Saudi Arabia, just as in the US we have the electric chair, hanging, lethal injection...

Kinda makes you wonder why the US media doesn't tell us that, and put these public executions being carried out against foreign nationals by the insurgents into a legitimate context, doesn't it?

Oh yeah--that might generate some public interest and debate on the death penalty in the US, and the ruling elite in the US want that debate to happen just as much as the Saudi ruling elite does...
