In Maryland V

In Maryland v. King (2013) , upon an arrest, the police conducted a DNA search and procured a sample of the defendant's DNA without a warrant. A routine collection of DNA following a valid arrest:

A) was held to be reasonable because no individual has the expectation of privacy of that individual's DNA pattern.
B) was held to be reasonable under the Fourth Amendment since the defendant was already in custody, and the taking of a DNA sample from the mouth was similar to taking a fingerprint.
C) was held to be unreasonable under the Fourth Amendment because the taking of a DNA sample is an intrusion into the arrestee's body.
D) was held to have been unreasonable in the absence of a properly issued warrant for the collection of a DNA sample.
