First, I don't accept the notion that building a DNA database implies that people who give have DNA samples their person violated without due process are suspects.

I fixed it for you.

Second, such a database can aid law enforcement in exonerating people, as well as identifying victims of crimes.

It can aid the government in doing other things in the future when Hillary is in charge too.

am not seeing any well-reasoned argument against the use of a DNA database

The forth amendment.

I'm not against databases, it is how the samples are collected and from whom. LET THEM GET A WARRANT IF THEY WANT TO SEARCH.

It seems to me that your main complaint about DNA databases is that they can be abused. In that case, the solution seems to be to legislate against the abuses instead of throwing out the baby with the bathwater. We don't refuse to give policemen guns just because some policeman commit crimes or torts with these guns. Same principle.

Nor do I see a Fourth Amendment problem with building a DNA database (I question whether the Fourth Amendment even applies to this situation), but even if it was a problem, the solution is to allow people to opt out. I certainly don't see a DNA database as any infringement on our liberty, as opposed to something that can actually enhance our liberty.
