Looks like 6000 possibly deliberately faulty drug tests. How many innocent people are in jail? How many guilty people are free in the community? It really beggars belief.

First noticed forsenic (scientific testing) questionable results when reading up on the Amanda Knox case. A number of worrying events happened in relation to the follow up, DNA testing after finding a wild card suspect from the prosecutor's newly minted story that he needed the facts to corroborate. He was also noted been in close promity to the noted technician. Just an advanced form of doctoring police notes from an interview that the UK is very familar with.

I hope that normal practice is for technicians to test by unidentified numbers to prevent the temptation to assist the evidence. Thus they find such and such a result for item id such and such.
