An question whose resolution will extend far beyond criminal law enforcement: Lawyers Fight DNA Samples Gained on Sly
The practice, known among law enforcement officials as “surreptitious sampling,” is growing in popularity even as defense lawyers and civil liberties advocates argue that it violates a constitutional right to privacy. Mr. Gallego’s trial on murder charges, scheduled for next month, is the latest of several in which the defense argues that the police circumvented the Fourth Amendment protection against unreasonable search and seizure.
Critics argue that by covertly collecting DNA contained in the minute amounts of saliva, sweat and skin that everyone sheds in the course of daily life, police officers are exploiting an unforeseen loophole in the requirement to show “probable cause” that a suspect has committed a crime before conducting a search.
“The law cannot tolerate such back-door methods, which seize something that any reasonable person expects to remain private,” Mr. Gallego’s lawyer, David Lynch, wrote in a motion to suppress the DNA evidence extracted from the cigarette butt.
