Hogwash

A lawyer friend sent me the paper this week, in a state of panic about the consequences,

As others have pointed out, if you have access to a subject's DNA profile and access to an oligonucleotide synthesiser then you could synthesise a DNA profile that matches a living individual and leave "evidence" at a crime scene. However it's going to be a lot easier to obtain DNA from an individual and scatter that around.

And if anyone thinks that the spooks don't pay attention to the purchasers of oligonucleotide synthesisers and of nucleoside phosphoramidites for those machines or to PCR systems and deoxynucleoside triphosphates for those machines then they are sixpence short of sixpence.
