"Investigators also found bomb-making equipment and martyrdom videos on computers belonging to some of those in custody, said Clarke. He didn't say whether the people in custody appeared in the videos."

If he didn't say, then the videos were probably of someone else, not connected with this group. Anyone with an in-depth interest in the Iraq situation might have these - I am sure they are all over the internet, like the beheading videos.

Bomb making equipment might be nothing more than some wire cutters. Hydrogen peroxide comes in handy for dying your hair, or treating a minor cut.
