Briefcase Sized DNA Analysis System 95

Posted by samzenpus from the portable-paternity dept.
An anonymous reader writes "Japan's NEC Corporation along with Aida Engineering have developed a briefcase-sized DNA analysis system that enables the police to perform comprehensive DNA testing at crime scenes in as little as 25 minutes. The same test would take at least a day to a week (if re-testing or conformation is required) in the lab. The system is compact enough to be carried to crime scenes or other locations where quick DNA analysis is required, making it the world's first portable DNA analysis system."

There is a reason why these tests take up to 2 weeks to give a result: Once you as a scientist say "we have DNA evidence, we got him!" it pretty much seals the deal.

      The parent might have said something to fire up the crowd, but in all honesty, don't be suprised if it appears at passport office as a part of getting your passport, then becomes a part of your driver's license acquisition, then lands in every police car and station and finally at the checkout counter as part of using your credit card or purchasing certain items. The real flamebait is going to be when a true patriot spits in the eye of the first bureaucratic employee to tell him they have to have a DNA sample from him. Ptui, there is your sample.

      Even the article states this can be used by law enforcement, so don't be suprised when DHS decrees that the parent is correct. Hope the samples aren't taken via blood as enough errors have proven fatal in the past in that regard and by professionals, much less low wage bullies at the airport. I hope this doesn't happen and perhaps the parent should have waited to say anything till it did, but I fear he is most prophetic in this regard. His prophecy may fire up the crowd, but we honestly should fear such abuse of our rights by the government and it is absurd that we put up with what they are already doing.
