North Carolina lawmakers are inching closer to a law allowing investigators to take DNA samples from suspects before any criminal conviction.
The House on Tuesday voted 92-23 to tentatively approve requiring DNA collection from people when they are arrested for serious crimes.
Opponents worry collecting DNA before a conviction tramples on civil liberties
But supporters say collecting DNA and comparing the results to blood or other biological evidence collected from crime scenes could prevent new crimes by catching repeat offenders.
Backers also argue DNA evidence has freed hundreds of innocent people nationwide.
A final House vote could come Wednesday. The measure then would need approval by the Senate and Gov. Beverly Perdue.
