Clearly, there can be no fraud because it was the evil male who used deception to get in the innocent and naive female's knickers in the first place.
Secondly, DNA evidence is to be used only in opposition to the death penalty to prove the innocence of blacks on death row. Any other use is dicey.
Next, we simply can't be in the business of questioning "single moms" (God bless 'em) in their difficult times about the paternity of any of their children. What they say must be fact because they are, well, single moms.
Finally, this is exactly why the evil Republicans should not have been allowed to appoint judges will allow the use of DNA evidence to disprove paternity. Dems know that it is OK to go back 20 years to use DNA to prove that an imprisoned black man didn't comit a crime and release him from prison but it is not OK to use the same kind of evidence to prove that an error was made in ascribing paternity to a given male.
