Why can't they get DNA the old fashioned way, extract it from a suspect while in custody, with or without his permission.

Obviously you did not get my jest. DNA information is now available from a Red Cross database? How inappropriate. The only way they should be able to do a DNA test is when they have they guy in custody. Why should volunteering blood and having it extracted at a bloodbank make everyone a suspect?

Actually I was joking back, but my point was that if DNA is gathered from a suspect, all records of his DNA should be destroyed if the suspect is not convicted.

Suspects in crimes are no more guilty, from a legal perspective, than your average blood donor. (OJ excluded)
