(Harrisburg) -- People arrested for serious crimes would have to give a DNA sample if a bill recently taken up by the state House becomes law. Some civil liberties advocates say it's unconstitutional. The measure would allow for DNA testing by taking a swab sample from inside the cheek of suspects after their arrest, but before conviction. Andy Hoover with the American Civil Liberties Union in Pennsylvania says the proposal ignores constitutional prohibitions on unreasonable searches and seizures. "This bill simply does blanket DNA connection across the board for all persons arrested for felonies or certain misdemeanors," Hoover says. The measure has passed the Senate, where it was sponsored by Republican Majority Leader Dominic Pileggi. He says it's a much-needed update to the Commonwealth's DNA testing procedures and database, which were established in 1995. "I think we all know the technological advances that seem to happen every day. Certainly, since 1995 it's an entirely different world in that scientific community," Pileggi says. He adds the federal government and 26 other states, including New Jersey, Ohio and Maryland, have modernized their DNA policies.
