What can turn a "normal, smiling Danish kid" into an Islamic extremist opposed to "his own society, the West and even fellow Muslims"? That is the question Denmark's authorities are grappling with.
In Norrebro, a mainly Muslim suburb of the capital Copenhagen, I met two young Danish Muslims on the street. They spoke to me about a conflict thousands of kilometres away, in Syria.
Despite its distance, the bloody conflict has become an issue for the Danish authorities in terms of security and integration in this liberal Scandinavian country.
