In regard to the government collecting DNA samples: I believe that if a person is arrested and booked on some charge, for the authorities to collect DNA samples is not much different than the person being fingerprinted.
For the government to randomly collect DNA without any particular reason or cause I feel should not be done. But for someone charged with a crime, it is a legitimate part of identifying lawbreakers for any possible future investigations of crimes.
We have recently heard of a number of cases where someone was convicted of a crime and was serving time in prison, and that DNA proved that person was not the guilty party, who was therefore subsequently released. DNA can be a powerful tool in helping to prove if someone is the perpetrator or not of a crime.
