Claymore-The Supreme Court has upheld the legality of random consent searches in such instances as asking an entire busload of people to allow the police to search their belongings. It has also maintained that a "reasonable person" is expected to know that they do not have to comply with a consent search, even if not informed, and has upheld convictions that occurred when someone, not knowing that they were not required to allow the search, turned over damning evidence (such as large quantities of controlled substances) to the police conducting consent searches. This principle would in fact allow police to simply ask a busload of people for a DNA swab.
