Freight is difficult to bulk screen effectively. There is a world of dfference between screenng passenger bags and pallets or cans of engine parts or similar bulk metal items that are impermeable by x-ray.
That's not to say it shouldn't be done, but it won't be until the government makes it mandatory. Wheeler recommended screenng for freight carried by passenger aircraft, but even that would take a huge cost and time investment.
I wouldn't expect a private company to introduce screening of its own volition, particularly when the time lag would make it less competitive.
