"Saudi authorities, facing a wave of militant attacks, have arrested five people after raiding computer shops selling compact disks containing hidden
bomb-making instructions, a local newspaper reported on Thursday."
Since bomb-making instructions can be found on the Internet what else might these CDs contain?
It could be they're afraid to surf to those websites, because they might be tracked. If they keep them on a CD, it won't be as easy to track them
down...maybe?
