Let's hope Norman Kember and the other three hostages, held by the Swords of Truth (SOT) group in Baghdad, are released soon. But you have to question their rationale for being there, their sanity and/or their motivations, and it's not surprising the kidnappers suspect the four 'Christian peace activists' may be spies. According to the Christian Peacemaker Teams' website:
Christian Peacemaker Teams has been present in Iraq since October 2002, providing first-hand, independent reports from the region, working with detainees of both United States and Iraqi forces, and training others in non-violent intervention and human rights documentation [sic]. Iraqi friends and human rights workers have welcomed the team as a nonviolent, independent presence. CPT teams host regular delegations of committed peace and human rights activists to conflict zones, who join teams in working with civilians to document abuses and develop nonviolent alternatives to armed conflict. The CPT Iraq Team has hosted a total of 120 people on sixteen delegations over the last three years. [my emphases]
The CPT missionaries sent back regular messages from Iraq, which are posted in a Yahoo group. (link) It seems they don't speak Arabic, don't have medical expertise, and spend their time talking via interpreters to the war's victims, preaching non-violence and reconciliation, and dodging bombs and bullets. I've no doubt Norman Kember is not a spy but, rather, a naive, misguided idealist - but such people ought not to be in war zones, being a danger to themselves and others. 'Getting in the way' in the frontline of the war on terror and getting themselves kidnapped isn't where Christ would have wanted them to be.
