The Supreme Court has just ruled that police have the right to obtain DNA from those they arrest. Apparently it’s a reasonable booking procedure used to identify a suspect. Even though the identification can take weeks. And it almost always will pertain to some other crime for which the police otherwise do not have any reasonable suspicion. And it gives them access to what is normally protected medical information.
Somehow, I don’t think if the founding fathers were around today that they would be in favor of the government having access to a private citizen’s DNA without probably cause, a warrant, or a conviction.
