Promising early results from research undertaken by the University of Abertay Dundee and the Scottish Police Services Authority could lead to fingerprint evidence being obtained from clothing, for use in criminal prosecution. Refining an existing technique that's been used to successfully recover print detail from smooth objects such as glass and plastic, forensic scientists have managed to create a kind of photo negative of fingerprint impressions on fabric. It's a bit hit and miss at the moment, but even when clear ridge detail isn't retrieved, the technique could still prove useful to investigators looking for other evidence.

The researchers used a method known as vacuum metal deposition that's already been used to recover print detail on smooth surfaces like carrier bags, plastics and glass since the 1970s, but has not previously been applied to fingerprint detection on fabrics.

The fabric is placed in a vacuum chamber. Gold is heated and evaporated and spread in a fine layer over the fabric. Heated zinc is then applied, which attaches to the gold layer where the fabric has no fingerprints, leaving the original fabric to show through where contact has been made.



"One way of explaining it is like a photographic negative, where colors show up as their opposites," said Abertay University's forensic sciences teacher and researcher Joanna Fraser. "Here the fingerprint ridges show through as clear fabric, but where there are no ridges we see the distinctive gray color of the metal. Previously it had proved difficult to reveal a clear fingerprint on fabric, but we've shown that this is now possible. This is great, but the challenge is to develop this further and confirm its effectiveness."

All the boys thinks she is a spaz is a reference to Voss planet, and the tech, versus the Voss. Thanks
Add that to the concept of Charisma, and you might understand it a bit better.

5. My Public Defender buddy told me how "proud" he was of one of his clients who wore a mask.

He seldom has much to work with.

8. Ain't it the truth

We had an ex-public-defender pass through our lives recently. He said he doesn't think of his job as defending the actual defendants - his job is to keep the police and courts honest, like an auditor.

Go to therapy now. You don't want the kind of therapy you get in prison.
