Well, want to know something ?
There are plenty of videos like that available, all of them "written and directed" by friendly Jihadis from all over the world.
Everything you might want to see: Russian soldiers heads being slowly cut off in Chechnya, Daniel Perl murder video, Israeli mother with children being slaughtered in a cold blood by Palestinian "freedom-fighthers".
You name it - it is all there, for the glory of Allah.

And be afraid - we are talking here about kids you or your kids will go to school with.
