The DNA in this case is not exculpatory. It is neither incriminating to the people charged But it had nothing to do with the other discussion I was having which I guess is why it was introduced.
The legal definition of exculpatory is clearing or tending to clear from alleged fault or guilt.
The accuser in this case alleges a three person gang rape where no one wore a condom and at least two of the perpetrators ejaculated. And yet no DNA from any of the three charged lacrosse players was found on her or in her. Only her boyfriend's DNA was found. To me, this tends to clear them from alleged fault or guilt. I think it strains credulity to think that this kind of violent attack could take place under these circumstances and somehow there is not a trace of any of these guys anywhere on the accuser. They would have to be very immaculate rapists.
