There are some key differences from fingerprints. For one thing, DNA holds intimate medical/genetic information. Not only about the arrestee, but about their entire family. None of whom have been convicted of anything.
I wouldn't want that information in the hands of the government... not to mention all the 3rd parties who could potentially buy, hack, or steal the database.
Read what you cut out of my quote. DNA can be used to violate privacy, but simply entering a profile into a database and comparing it against crime scene collected samples doesn't. If the police department, for some reason, decided to run tests to see if you had genetic diseases, yes, that would violate your privacy.
The same applies to blood draws for alcohol, frankly. Your DNA is already in there. Do they run it for genetic diseases when they test for alcohol? No, of course not. Its expensive, time consuming, and pointless. Why would they run those tests on saliva DNA samples then? The tests aren't the same, would require extra cost and extra facilities and extra expertise for what gain?
Even if your DNA profile was hacked, so what? Your entire DNA strand isn't used for identification, and the information stored can't be distilled down to if you have a genetic disease. Something like 1/10th of 1 percent is used for identification, and its not like its a file jacket that reads "timmy has a high chance of developing this genetic disease". Its basically a string of letters, and like a fingerprint, is only useful in comparison to another string of letters.
I think a lot of your worries would be put to rest if you researched what DNA identification actually gathers and how it works.
