I've been wondering all day how the crime was uncovered, and it seemed most likely that the driver was instrumental in that. if so he could be either consumed with remorse at what he has been a party to, or horrified at what he has been an unwitting contributor to.
In either case, I think it is...
Very much this. The Channel Four News tonight was excellent on all this (it's usually excellent about most things) and they had a brief interview with someone from the Red Cross making the same sort of point.
Awful!
Is it possible that the driver did not know what was in the container!
But I just hope and pray they get the people behind this and deal with them accordingly
