According to media reports, the insurgents/terrorists/criminals/kidnappers weren't even present when troops rescued...er, released the CPT members.
What kind of kidnappers don't guard their hostages? More to the point, what kind of hostages don't try to escape when their kidnappers don't bother to guard them?
This stinks on ice. Frankly, it reminds me of the whole Susanne Osthoff episode. (She's the German who was supposedly kidnapped by insurgents. She was found to have thousands of dollars of the ransom with her after she was "released".)
Despite the murder of Tom Fox, how sure are we that this wasn't some stupid publicity stunt by the CPT?
How are we to know Fox's killing wasn't an element of a scam by these ideologically illogical zealots? Perhaps he wanted out.
