With all the security at borders nowadays, how the absolute fuck can a container full of people cross the border without it being inspected? They stop regular passenger cars and check them all over, so how in the world was the truck not opened and checked? Absolute shambles from the UK that.
Only just catching up on this as been away. We need to see exactly what has happened before we judge anyone guilty.
Trailers are sealed at point of loading and as long as the seals match the paperwork and there is no obvious tampering with the seal, then there is no reason to open the trailer. Curtain siders can be cut into with a knife or access gained through the thin roof, but a fridge trailer is solid due to the construction methods and if it all looks clean, then there is no need to go in the back. The trailer will not have gone through as empty, as this would trigger on the weighbridge.
They are designed to stop the load spoiling by denying heat from outside from getting in, the doors have really thick seals, so they are basically airtight, and depending on the load being carried, the fridge can be turned off on the ferry, so they could have done this without attracting attention.
As for the driver, on the surface it appears suspicious that he stopped and opened the back, but that is plausible. You know from your paperwork what you have on, it will all have been secured to stop it moving during transport, especially on the ferry. If he has put his foot down accelerating, the bodies will have shifted and that would make a loud bang as they hit the back doors or the sides. Get that happen a couple of times and you know something is wrong with your load, you would stop and with permission, you would break the seals and open the back.
