Question

Should a person's DNA be removed from the National DNA Database once it hass been proved that they are innocent?

Answer 1

No, because their DNA could be used for other useful things for the person.

Explanation:

There are many ways in which a person's DNA sequence (genome) could be used to benefit them or the community at large. One of these ways would be personalized medicine, which is when a doctor reads your genome and other biomarkers, such as DNA, RNA, protein products, or enzymes, and then uses that information to make a medicine tailored to them. Or, their genome could be used to trace their ancestry. Or, if the person were to commit another crime, then having their genome in a database would greatly speed up the process of jailing the person and preventing wrong accusations.
