Via Security Curve, take a look at the Intelligent Fingerprinting site, where they advertise:
The company has developed a series of reagents for the detection of illicit drugs in fingerprints which will be available in 2010:
- IntelliPrint ™ Cannabis assay
- IntelliPrint ™ Methadone assay
- IntelliPrint ™ Cocaine assay
So… does this mean that if you leave your fingerprints anywhere in public, you have no reasonable expectation of privacy from the government testing your fingerprints for drug use and then using that evidence against you?
Lawyers? Anyone?
