Yes, they are all gruesome, but has there been one in particular that has really burned a mark on your brain? Mine is without a doubt the Eugene Armstrong beheading. It's not really the blood everywhere that gets to me. It's the screaming and gurgling that gets me. Can you imagine what it would have been like if the terrorist wasn't covering Armstrong's mouth? What beheading video has made the biggest impact on you in any way? Post it.
