As a soldier, I gave my DNA to the government many years ago -— don’t want any more in the tomb of the unknown when there is a way to identify any remains found and bring closure to grieving families. However, Uncle Sam doesn’t share any information with ME!!! Therefore, I had to buy DNA service to find out the things I am interested in. IF I have a relative, near or distant, that committed a heinous crime and is hiding, I can’t feel bad if my DNA finds that criminal and aids in the prosecution. Just my opinion.
How are you going to feel when their "Crime" was fighting with Nazis intent on rounding us up and sending us to camps?
Sure, ordinary crime should be punished, but I am alarmed at the rate at which "thought crimes" are being created, and likewise I am alarmed at the punishment's being meted out to anyone declared guilty by social media of these thought crimes.
In England they are arresting people for talking about Muslim rapes.
DoD policy is not to share their DNA information, including with law enforcement. There may have been a few exceptions, but they are exceedingly rare. Law enforcement has turned to a commercial company that maintains a DNA database built from DNA tests that have been voluntarily submitted to them by individuals. Anyone can access this database. Suspects often leaves their own DNA at the crime scene. Old fashioned detective work can work with a list of potential suspects, known relations (traditional genealogy plus online search of websites that collect information on everyone), and comparisons of the suspect's DNA and the DNA in the database. Such databases are becoming larger over time and the probability of murderers and rapists remaining on the lamb is being reduced. Good thing.
Fortunately, my time in the service ended long before DNA comparisons became feasible.
