I saw a video of such an execution some time ago. Two men and a woman were tied to some kind of sturdy pole,a rope around each neck. A guy gave the signal and they were slowly lifted off the ground. The two guys were still from the very start but the woman thrashed about for about a minute before she,too,went still.
Barbaric doesn't even begin to describe it.
When Saudi Arabia had a dissident reporter whacked, the Left Media were all clutching their pearls...
But when Iran whacks a reporter... oh well...
