Michael, Michael,

You risk tying yourself up in knots here. Put down the Guardian down one second.

I think many people are uncomfortable with the state's enthusiasm for enlarging its DNA collection, but in saying that this will (locally) result in the misapprehension taking hold that "most criminals are black" is to imply that many of the 2000 sample "donors" are criminals when this is surely not the case. Are you not running the risk of worse labelling / libelling in your efforts to remain PC?
