I skimmed this thread, and for the most part it looks like the usual paranoid rantings from libertarians and conspiracy theorists. I am not seeing any well-reasoned argument against the use of a DNA database to help law enforcement catch criminals, including but not limited to why any solution short of doing away with such databases altogether would be a bad idea.
I find it amazing that anyone would have to have explained to them the pitfalls of bureaucrats having all of our personal information at their fingertips.
Why don't we just install cameras in your house. Hey it may help catch criminals and "secure our individual rights from those who would deprive us of these rights, including criminals" as you put it. Why not send a daily log as to our comings and goings to the government every day. It may help catch a criminals after all. You'll probably feel even more secure.
I almost regret putting these ideas out there. I get the impression you might come back with "tell me how cameras installed in our houses deprives us of freedom" or "filling out a log may help secure my freedoms".
It's very simple. My medical records, DNA, bank account, credit card purchases or any other personal info are my effects and none of anyone elses f***ing business, including some uneducated bureaucrat's.
Let me spell it out for you, since you can't seem to figure these things out for yourself:
Amendment IV - The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
"We might need this information some day" is unreasonable and doesn't warrant probable cause for them to seize anything that's mine if I choose not to give it to them.
Forget the constitution, you have a basic human right to not have strangers rifling through your personal and private life.
You're making an extremely dumb argument. If you want to give the morons your most private information, knock yourself out. While you're at it, give them access to all of your finances, medical records, computer and anything else they and have everyone in your family do the same thing.
Then, when I get a government job as some database geek and decide I want to get even with internet posters who ask dumb questions, I'll find out where you're vulnerable and take appropriate action.
