I feel like I'm asking something you already answered, but just to make sure: this implies, that to frame specifically you I don't need everyone's DNA, I just need a sample of yours, right? And if I understand correctly, DNA evidence is treated with quite a respect in court? So, if I really can make a sample of "fake DNA" (that will be indistinguishable from the "real" for forensics purposes) for a couple hundreds dollars, I really can frame anyone I know for anything (right now!), because getting a sample of their DNA isn't really that difficult. It doesn't quite add up in my head, because if it's so simple, why the courts would even consider it hard evidence?
