How could that happen? If they have your DNA and find it at a crime scene and correctly identify you, wouldn't it mean that you were at the crime scene at some point? Perhaps at least you should be contacted to find out what you know. Perhaps for some reason your DNA is there and you have no alibi. This is not just a risk of DNA though: It would be the same effect if a witness saw you but did not see the actual criminal. It will be extremely difficult to categorically avoid this kind of mistake and keeping your DNA out of the public is not going to help.
Are you worried that the test will fail and generate false positives? That is a different issue from sharing your DNA with the government, and one that must be addressed.

Partial matches are one concern (where someone comes and asks you questions because they think one of your relatives that you've never met may have committed a crime), but laboratory errors and general investigational misconduct are the big one (e.g. http://www.cbsnews.com/news/dna-testing-foolproof/ http://www.cbsnews.com/news/dna-testing-foolproof/ from 2003, or a Brandon Mayfield like situation with DNA instead of fingerprints).
