I see little difference between collecting fingerprints and DNA samples.
Very few reasonable people object to suspects being fingerprinted, so far as I can tell.
Maybe people don't actually know what's being stored? A couple dozen non-protein-encoding loci cannot be used to frame you, tell what gender or race you are, or derive any other information about you.
You can't look at a CODIS entry and say "this is a red-headed female with green eyes and a higher-than-average risk of breast cancer" you can't tell anything-- except if the samples being compared match.

Same as fingerprints.
