I saw those too, the one of the older woman (in her 60's probably) was one of the worst ones I saw, she reminded me of my mom.
I've seen the videos of the Chechnyian (sp) soldier being shot, stabbed and eventually be-headed. Luckily, most of the videos I've seen I've been able to forget, because that shit is horrific. Sound or no sound.
I watched too much of...faces of death (?) back in my younger days. I've seen videos of animals (dogs and cats) being skinned alive, and still being alive while their fur is off...I've seen kittens being used as shark bait...that's why I tell people, when they talk about gore in movies or send me a link to something...it doesn't phase me. People are fucked up.
