Iowa Attorney General Tom Miller says Wednesday the proposal would help police solve more crimes. It would add adults convicted of an aggravated misdemeanors for offenses such as theft and assault to the federal DNA databank.

The American Civil Liberties Union opposes the bill, saying it's an invasion of privacy and could prompt too much DNA profiling in the future.
