  1. Holy guacamoley Derek you’ve been working on this for a couple of years?
    I don’t think we really appreciate what you guys are doing here then, I’ve had no idea that some of your projects take such an amount of work and time.

    Thank you for this opportunity to learn more about DNA sampling and everything else!

  2. That reporter / cop is such a great investigator.

  3. PANdaramic Firefox

    With those unique parts, how possible, if at all, would it be to reconstruct a face with only DNA to work with?

  4. What about hacking?
    What about manufacturing DNA samples from leaked data?
    What about corruption?

  5. If you don’t want a gun after that crime description something must be wrong with you.
    80% of gun crime is committed with illegal obtained firearms, restrictions never work.

  6. Im on my period right now. Who wants a sample of my dna?

  7. China has been buying DNA companies. They now have access to millions of western peoples DNA.. I wonder what kind of illnesses they will come with based on that information….
