No, the government should not be able to collect DNA from non-violent and non-convicted offenders, because that is too much government intrusion. The government should have a good reason before they collect that information. It is scary to think what the government might do with information like that. They should have to have a good reason before collecting it and keeping it, otherwise it's too much intrusion in our lives.
Not only should the government not be allowed to collect and maintain samples from Non-Violent and Non-Convicted Offenders. The government is in violation of the rights of those individuals civil rights and the practice should be outlawed and disbanded completely. The collection of this data has no societal merit and is over reach by the government.
