    Really cool tech, I wonder if law enforcement could use it to detect a range of time someone has been at the scene of a crime based on the concentration of dna found. Could really help solve some crimes when you’ve got no leads.

      Forensic sciences are in general a big scam used by prosecutors to put innocent people on jail. Hope this dosen’t become the new “hair evidence”.

        There’s a big difference between DNA testing and things like “body language science,” and polygraph testing.

        Like a massive gulf.

        Yeah, the American Bar Association said “Telling a jury it is implausible that anyone besides the suspect would have the same DNA test results is seldom, if ever, justified.”

        Cross contamination could likelyonly get worse if you include airborn or otherwise mobile DNA as part of your samples.

        Blood splatter analysis and dna are two entirely different things though.
