According to the article, the suppression motion is based on the argument that when the police used DNA evidence as probable cause for the warrant(s), they violated the suspect’s 4th Amendment right to be secure from any unreasonable search and seizure. I suppose the question then is does a person have a reasonable expectation that their genetic information, or such DNA they might have left behind in a place outside of their dwelling, will remain private. I think not, and the argument verges on being frivolous.
already been determined long ago that if you throw something away you lose all rights to it, including DNA on those items.
