morten storm wrote a book about his experiences, partly to protect himself. morten: i had some information that was very vulnerable, that could even damage the danish government and also worldwide. so maybe some people were intersted in taking me out. so i said well, my only defence is to go on the offense, to go public. reporter: islamic terrorists reacted by sending him a video, seemingly recorded in syria. on the wall are photographs of storm and a number of other high-profile danes. the message is clear. but despite the threat to his life, morten storm says he's been offered no police protection. he'd like to lead a normal life. but that's unlikely to happen any time soon. anchor: when i saw this report the first time i thought "how can a nice guy like that become a jihadist?" do you understand how young people from europe end up in a war that isn't theirs? feel free to discuss it with me on twitter. if you live in the small country of estonia, in europe's east, there's a pretty high chance you'll die of an overdose. statistically speaking of course. drug
