Re: Foresic Science UK & US
I also read the article this week, and I was quite amazed at the pressure that forensic teams can be under, particularly the pressure by police that want evidence to point to a certain outcome. The fact that any of the 365 scientists surveyed said they sometimes felt pressurised to produce a particular result is very worrying.
There was an article (in new scientist) several months ago about how DNA evidence is debatable, in that when partial DNA is recovered from a scene different labs came up with different levels of probability for the partial DNA pointing to a particular suspect, to the point where some would have said the evidence pointing to the suspect being present at the scene and others that he/she wasn't.
We are lead to believe that DNA evidence is irrevertable, but it seems that isn't entirely true, and there is still room for interpretation of the results.
