Better hope none of these kids did the deed, because if the DNA links them to the crime: Poisoned Fruit bad cops, poisoned fruit.

 How is it that you can stick a needle into someone without their permission, but can't stick a penis into someone without their permission?

 Two points:  a. If this Sheriff considers these children mature enough to 'give their consent' for this then he must also consider them mature enough to consent to sex & b. If they had taken a DNA sample from my child without my consent the Sheriff would be scrambling for his passport and a one way ticket out of the country.
