> That's the case in France where DNA samples are taken on any person arrested, whether they committed a crime or not, including demonstrators (or bystanders) in a political march.
FWIW ~20 US states do the same, this was ruled legal in 2013 (Maryland v. King, DNA collection is part of police booking procedure).
CODIS (the FBI's DNA database) contains more than 17 million non-forensic profiles[0], that's also >5% of the population.
But wait, there's more!
The Department of Defense's own DNA database (DoDSR) has more than 50 million records (collection started in the 80s and every applicant to a uniformed service gets included), and since the 2003 National Defense Authorization Act can be accessed by federal or military investigations for "the purpose of an investigation or prosecution of a felony, or any sexual offense, for which no other source of DNA information is reasonably available". So it can't currently be searched / "wild matched" against an unknown sample but if there's a suspect, a sample and no other DNA source then it's an option.
