call me paranoid but I think once you submit your dna its open for the govt...
I’m an Army Vet and use the VA for my healthcare.
I’m in Breast Cancer and Colon Cancer research groups. (Control groups, as I have neither disease. Yet. Until they want to give me either, LOL!)
They have all the data on me they could possibly need for Good or Evil. ;)
Everyone who joins the military has a DNA sample on file. It's routine. It is really no more or less significant than having fingerprints or pictures on file--it's a way to identify you. Having DNA on file is handy for forensic purposes... I won't go too much into details.
