Recent reports from forensics experts have shown your DNA can be taken from the air where you have physically been.

So you say you weren’t at a particular place at a certain time? Well, DNA taken from the air can prove you were there. Of course, since you can’t prove a negative, you won’t be able to prove you weren’t there, but airborne DNA can certainly show you were.

 

 

Scientists have known for years we leave a trail of sweat, oil, hair and skin wherever we’ve been. So if you’ve been at the scene of a crime, even if you’re innocent, your DNA is now part of a nationwide police database called.

Police currently use some 20 DNA markers to make a positive identification from a crime scene. But researchers were recently able to collect the 20 relevant markers from an individual’s DNA from the air of an ordinary office.

 

 

And they weren’t using a machine the size of a room costing millions of dollars. You can buy a genetic sequencer on the open market for less than a thousand dollars. It is the size of a cigarette lighter and plugs into your laptop computer.

Unfortunately, believe it or not, there is as very real legal question of who does your DNA belong to once it is no longer on your person.  Some authorities consider it to be abandoned property, meaning anybody can collect it for whatever purpose they want.

Government authorities, of course, want to take an expansive view of who DNA collected from the air belongs to. Privacy experts want restrictions on who can collect such data, and what it can be used for.

Once again, we have an example of technology out-pacing the law, and experts from both, or all, sides of the issue are weighing in with their own view of reality. – I’m Larry Burriss.
