It is very hard to get cases reopened, it is true. Once DNA testing came about many convicts tried to get the evidence in their cases tested to prove their innocence, but this took many, many years in a lot of cases. In fact, getting anything fixed or changed after conviction is a long process. I know someone who was given 100 years extra on his sentence due to an error by the judge, instead of the ~15 he was due. That was two years ago and a simple error like that still hasn't been rectified.
