Thieves have more to worry about than fingerprints

In the course of robbing a house, it may seem like a small thing to snag a can of pop. But leaving that can behind can also leave the evidence necessary for a conviction. A recent Associated Press article, Police use DNA to solve everyday property crimes, detailed the increasing use of DNA by Denver police in burglary and car theft cases. A Denver suspect was convicted of five robberies because he left pop cans behind at each scene. DNA analysis of his saliva then linked him to all five cases. Other convictions came from a lollipop and a tuna sandwich. The average stolen property sentence in Denver in a case where DNA was used as evidence was 14 years as opposed to an average 11/2 years without DNA.
Using DNA has become more possible now because it is less expensive, requires a smaller sample, and takes less time than before. On the low end, it can take only 12 hours and 50 dollars. The CSI exhibit currently at the Science Museum seeks to show visitors how the techniques seen on the show are used in real-world forensics, so I thought it was interesting that the article included this quote:
"Regular watchers of CSI may be led to believe that this technology is already being used in this way, but it's really brand-new," said John Roman of the Urban Institute, lead author of a study on the issue. "This really is the start of a revolution in policing."

Thats great that we only need little amount of something to figure out so many things

That is really amazing that someone could be linked to several crimes based off of a tuna sandwich, lollipop and can of soda. Although it's great that we have the technology to figure these things out with such little data, it's a little bit creepy to think that our whereabouts can be determined by such little clues.

Science and the world of DNA has come a long way! It is amazing and used in the right way we can single out the offenders and make the streets better for generations to come.

Wow, the Denver cops are just like CSI! I wonder how much it costs for all this DNA analysis. Sounds like a cool job to investigate crimes.

It's amazing how much crime solving has changed. You are hearing of how people are being convicted of crimes that happened over ten years ago. There was DNA collected but there was no way of testing it. Times sure have changed.
