AP reports something to obviously be expected, but had you thought "Who'd know"?
As a hypothetical: If a swab is taken for testing, would one expect it is only for Covid-19 testing, with no DNA profile of you also taken for entry into a forensic data base for later testing against DNA from a crime scene or in some criminal investigation? If one swab fits all, and say you left a leaflet at some protest but personally got away, would there be a search for a DNA match against leaflet fingering residue? Part of the hypothetical, would they be telling us if they were using swabs for dual duty? For context, recall that Clapper lied under oath about phone sweep activity, to Congress, and got away scot-free. Does that latter fact make you comfortable?
Days ago the Patriot Act ultra-surveillance secret bullshit got renewed. Whether that gives you comfort or not, you decide. Is it worth the time for you to research how your Senators voted? Or can you simply guess? Amy and Tina? No need to look up Minnesota's two.
