No on the second, for good reason. There wasn't anything in the article that indicated that the prosecutors did anything wrong. They took the evidence they were given by the police, by informants, and by the crime lab employee and presented it at trial. That the police did not give the prosecutors all the evidence the police had, and that a forensic technique that was widely accepted at the time by the FBI and the state turned out to not be accurate is beyond the scope of the prosecutor's role.
For this prosecutor's office to have put this fellow away for so many years on not even circumstantial evidence but merely the good faith acceptance of three unreliable sources with criminal records, and the hair which turned out to be erroneously identified, despite the bloody handprint that was not a match, and despite the victim's failure to identify the defendant, is almost obscene. Sadly, however, it's not unheard of at all; our criminal justice system is far from perfect, though it probably still ranks near the top in a world where justice is difficult to obtain in most countries outside of western Europe and North America.
