My only question is about the drivers, did they know what they had on board. They may have known it was illegal cargo but not the nature of that freight. If I had been on the jury I might have argued for manslaughter in their cases. It would depend on the evidence, it might be it was clear they did have full knowledge.
When I read 78 years in the headline, I though wow that's good, but then I realised it was between four of them, not good enough in my opinion. Those poor souls died a truly terrible death. RIP.
