Familial DNA used to solve a crime, privacy questions raised.

[BabyPiNK_FL]

If your blood is in the system for crime, I say fair game to use it for a match for a family member who may be in danger (kidnapping scene w/ blood, etc.) or to find a potential suspect who has left DNA evidence at a scene.

If your blood is at a crime scene and you aren't the victim or it appears highly suspicious... let's safely make the leap...

I wouldn't call this overstepping the boundaries or anything. You don't want to be in the system? Do your best to keep your nose clean. You don't want your blood from a crime scene (non-victim) being traced back to your family, don't commit crime.
