I didn’t watch it either because I got better things to do, but a comment on youtube was very informative:
1) Foley showed no sign of any expected negative emotion: fear, apprehension, nervousness, regret, sadness, panic, etc. as he was prepared for execution
2) He did not flinch when the knife was pressed against his neck. How is that possible without the certain knowledge that nothing was going to happen??
3) The video ended prematurely - before his head was decapitated. Why? Because they didn’t want to offend our sensibilities? C’mon. And anyway, that never stopped the terrorists before.
I think Foley is still alive. He was an Islamist symp. According to sources, he last statement was an anti US screed. If he knew he was going to dive anyway, why the hate speech? Or, he is dead but didn’t think his friends were actually going to kill him - that’s why he’s so calm before the “execution”
