There is only one basic human right, the right to do as you damn well please. And with it comes the only basic human duty, the duty to take the consequences.
P. J. O'Rourke
No it wouldn't.Not all criminals leave finger prints or DNA. Not all finger prints or DNA collected from crime scenes are whole finger prints or whole DNA.If anything a database would make it easier for someone to plant your biometric information at a crime scene. Even then that stuff if circumstantial,for example a finger print on a shell casing proves you touched it it, does not prove you loaded the bullet into the gun and it most certainly doesn't prove you fired the gun.Wouldn't a universal DNA database make it less likely that I'd be investigated unless I committed a crime?
So you are suggesting that we should give up personal information in hopes that the police won't investigate us for anything? In that case lets mandate GPS in our cars and tracking chips in everyone.Wouldn't that increase my privacy?
"A nation can survive its fools, and even the ambitious. But it cannot survive treason from within. An enemy at the gates is less formidable, for he is known and carries his banner openly. But the traitor moves amongst those within the gate freely, his sly whispers rustling through all the alleys, heard in the very halls of government itself. For the traitor appears not a traitor; he speaks in accents familiar to his victims, and he wears their face and their arguments, he appeals to the baseness that lies deep in the hearts of all men. He rots the soul of a nation, he works secretly and unknown in the night to undermine the pillars of the city, he infects the body politic so that it can no longer resist. A murder is less to fear"
Cicero Marcus Tullius
