In a nutshell: `(A) The Attorney General may, as provided by the Attorney General by regulation, collect DNA samples from individuals who are arrested, detained, or convicted under the authority of the United States. The Attorney General may delegate this function within the Department of Justice as provided in section 510 of title 28, United States Code, and may also authorize and direct any other agency of the United States that arrests or detains individuals or supervises individuals facing charges to carry out any function and exercise any power of the Attorney General under this section. What this means is that if anyone is detained for any reason, including a broken taillight or violating curfew, they can take DNA samples from you. I have no doubt that as soon as it is allowed, an easy way to take DNA samples will surface, and anyone who is ever stopped for any reason will be forced to have their DNA taken, even if it is a bogus charge. Once they get the DNA, you can't make them give it back. How do you think the nation is going to feel about Big Brother having DNA from their children (or even their own) in a database somewhere? IMO, this alone could kill this initiative.
