The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized. Actually several things come to mind here, from drug testing for work to taking drugs as a condition of parole for perverts. In these cases, the government skirts the 4th by saying it is voluntary acts. So what gives a citizen the right to violate the 4th Amendment Supreme law, or the employer to insist he violate the 4th as a condition of employment? And how is taking a citizens finger prints not a direct violation of the 4th Amendment, when arrested or suspected of a crime, or the government thinking they can store this data long after a trial and release from custody?
