I sometimes wonder in these instances whether it's doing the hostage more harm than good by promoting the story in such a way that it becomes front page news with campaigns and such stuff. I mean, look at what happened to Ken Bigley after the media gave 24/7 coverage, it seemed to hype up the terrorists.
In comparison, some hostages are released following little or no coverage. Just IMO, although I know it's not as easy as all this and his family and colleagues obviously feel the need to do as much as possible.
We can only Alan Johnson's released unharmed.
