Whenever something was broken in my childhood home of 5 kids, and no one would own up to it, my mother would spank us all to be 'sure she got the right one'. Perhaps this is just not strict enough. Put them all on death row to be sure we 'get the right one'.
What is wrong with you people?
How about a tatto of your name on your forehead at birth so people could ID you when you committ the crime. Better yet, how about a geolocation chip under your skin so when you committ the crime you can immediately be ID'd as being at the scene. Hey, if we keep going we can make this a completely crime free society, kind of like in the book 1984.
Feel free to mail a cotton swab of saliva to your state police laboratory for their archives. Just don't ask me to do it. And the downside is? my civil liberties?
No, mine.
"And the downside is? my civil liberties?"
States sell driver's license information every day. How far fetched is it to believe that they just might sell your DNA profile?
Maybe you couldn't get health insurance or life insurance. Perhaps you wouldn't be able to finance a home. What if your DNA found its way to a potential employer??
Talk about the camel's nose...
If the police have the resources, checking the DNA of women would be useful, too. Women would be more likely to volunteer, knowing that they aren't an actual suspect, but that a blood relative might be the Killer. Finding DNA that appears to be a close relative would greatly narrow the search --- maybe.
I don't know what the big deal is either. Why wouldn't anyone want to help out in such a simple way?
Why stop there? We could just implant radio transmitters in everyone's butt-cheek at birth.
