Is There Liability for Searching Passengers on Railroads?

Section 230 C2 is a statutory workaround for the constitution. It was explicitly designed to allow private companies to take down content that the federal government otherwise couldn't take down.

Others may not have been directly funded, but that detail matters less than the truth in this case.
