The Justice Department doesn't have a great history on forensics
The current US Attorney General seems to be doing some stupid shit when it comes to investigating the possibility of false convictions:

I happen to agree with a lot of press commentary that it's outrageous - it's just that it seems to be almost par for the course when it comes to the possibility of false convictions. As an example, see the actions of the US Attorney General under Obama from September last year:
