I would ask that action be taken on this matter. Our freedom of speech, and our freedom from unreasonable search and seizure, are bedrocks of our Constitution. Just because someone is at a port of entry, why does that mean that their basic rights, long enumerated in our cherished Bill of Rights, should suddenly be ignored? As a US citizen, I should always retain those rights when on American soil, regardless as to where that soil is. Please work to rein in these unreasonable acts by CBP.
