Requiring DNA samples: Helping to solve crimes or high-tech profiling?

Arkansas is the only state in the region that hasn't considered legislation requiring police to take DNA samples from those arrested (but not necessarily convicted) of crimes. Proponents say this measure would provide law enforcement with a database of evidence that could solve open cases across the country. Opponents believe this is a big brother move that would make a suspect out of anyone arrested for a serious crime, even if that person later is found innocent. It doesn't seem any more intrusive to me than fingerprinting an arrestee. Congress and 12 states have enacted legislation that would require DNA sampling, and 22 others have taken this issue up in 2008. Here's more from stateline.org.
