the Federal Bureau of Investigation will join 15 states that collect DNA samples from those awaiting trial and will collect DNA from detained immigrants — the vanguard of a growing class of genetic registrants.Essentially this means that if you are arrested and charged with a crime, your DNA could be recorded by the FBI and stored in a database. As an expert quoted by the Times said,
“Over time more and more crimes of decreasing severity have been added to the database. Cops and prosecutors like it because it gives everybody more information and creates a new suspect pool.”It expands the "suspect pool" to include many more innocent people. If you were charged with a crime but completely innocent, it won't matter. You will be a possible suspect in future crimes, because your DNA will be sitting in a database along with actual convicts. Hopefully the ACLU will find the time to act against this disturbing expansion of police power, in between defending terrorists and trying to cripple the CIA.
