I didn't have the cotton swab shoved up my nose either. Agreed on keeping the psychos away. Unfortunately, a lot of us had already willingly given our dna via things like ancestry.com. They even exist for pets. Also, we give our blood willingly either when donating blood or getting it drawn for lab services. Sometimes those labs are saliva, hair, tissue samples, etc. I am not a scientist, but my guess is dna is obtainable from all these sources. So, I think they have access to our dna via multiple avenues, unfortunately.
