So! Just what defines a dangerous or illegal act at YouTube? If you take them at their word (and based on a hell of a lot of experience we do not) it would seem that terrorist training videos are a no-no.
“we draw the line at content that’s intended to incite violence or encourage dangerous, illegal activities …. videos that train terrorists …. Any depictions like these should be educational or documentary and shouldn’t be designed to help or encourage others to imitate them.”
Since the users/videos below have been up for quite some time – we are to take it that they are of an educational or documentary nature? Oh! And click the pictures to enlarge – I think you’ll find – they’re interesting.
