UK Asylum Seekers: Let The Right Ones In

The Home Office, the UK government department responsible for immigration control, has initiated a program to test the DNA from of potential asylum seekers in an attempt to confirm their true nationalities. The initial program is a six-month pilot limited to claimants arriving from the Horn of Africa. The program, currently using forensic samples provided on a voluntary basis, could potentially expand to other nationalities if successful. The Home Office spokeswoman said ancestral DNA testing would not be used alone but would be combined with language analysis, investigative interviewing techniques and other recognized forensic disciplines, but many are decrying the "deeply flawed" program, from refugee support groups to scientists in the genetic forensics fields (via). Sandy Buchan, of Refugee Action:

Many of those who seek asylum are two or even three generations removed from the country of origin of their parents and grandparents, and are fleeing areas other than the nation of their birth. A Zimbabwean farmer fleeing persecution may possess the DNA of British relatives; would they be denied asylum on that basis?

Alec Jeffreys of the University of Leicester, who pioneered human DNA fingerprinting:

The Borders Agency is clearly making huge and unwarranted assumptions about population structure in Africa; the extensive research needed to determine population structure and the ability or otherwise of DNA to pinpoint ethnic origin in this region simply has not been done. Even if it did work (which I doubt), assigning a person to a population does not establish nationality - people move! The whole proposal is naive and scientifically flawed.

CSI Myths: The Shaky Science Behind Forensics Forensic science was not developed by scientists. It was mostly created by cops, who were guided by little more than common sense. And as hundreds of criminal cases begin to unravel, many established forensic practices are coming under fire.

It's not gross, it's science!

No reaction allowed is the rule in Mr. Rubin's forensic science class at New Rochelle High School. Many high schools around the country are offering forensics science, including Eagle High, which will be starting next year. John F. Kennedy High School's forensic science class has their own blog.

The American National Academy of Sciences recently released a report that punched a few holes in the credibility of the forensic sciences: often seen (and portrayed) as infallible, in practice they're non-standardized, subjective (warning: pdf with gory image), accepted without rigorous testing (pdf), and lousy with dilettantes. A Canadian inquiry into the work of a pathologist whose testimony wrongly convicted a man of anally raping his four-year-niece to death says that forensic science is useful, but that we're doing it wrong. It's beginning to dawn that what we used to think of as a few bad apples may actually be symptoms of a deep rot in the field itself. As for the wrongfully convicted Canadian, after 12 years in prison for a crime that didn't exist, he forgave (.mov).

I sense you want to plead the 5th

For the first time in the Indian state of Maharashtra, life sentences were meted out based on the findings of Brain Electrical Oscillation Signature(BEOS) profiling. "During BEOS profiling, an accused is asked not to give answers verbally; experiential knowledge is retrieved from his brain. ... The technique detects and differentiates whether the accused was actually involved in committing a crime or only learnt of it. It helps in the reconstruction of events." The developer of the technique appeared on the BBC Radio show All in the Mind a PubMed search turned up nothing

question your science professional MD, PhD, specialist. I've always thought you should seriously question their input on all their advise but most ppl don't.
