I wonder if there is a way to render these scanning devices ineffective or shroud items from them. I don't see why it would be a problem to scan-proof vehicles, containers, or clothing, considering that they don't have a warrant for the search in the first place. I guess lead-lining everything is pretty inconvenient, but I don't see why the pigs get to see me naked for free.
