Seaports are Our weakest link which need tight security,airports already have x ray so don't understand your point in bringing airports into the debate,espicially when I was clearly referring to seaports.
Cargo and passengers come into this country by air and sea. The seaports in this country have far more industrial level sophisticated X-ray capability than airports because of the vast volume of containers that are shifted. That said, a lot of cargo travels by air and therefore the opportunity to bring weapons and bodies in via containers is also a major threat.
I'm sure you though you were only talking ports, but it wasn't clear to me.
