Innocent people are set free on evidence - not on lies! What lies did the Birmingham Six, the Gilford Four, Stefan Kiszko and the like, put forward to obtain their release? It's OK to lie in order to further your case? WOW!

Innocent people are sometimes set free because of
lack of evidence, or because of technicalities. I wouldn't assume they're telling the truth about absolutely everything.
If Jeremy is innocent, what can he do to show that? He's tried the DNA thing, he's tried other things, and he's going to try everything he can. The appeal court will not buy it, but that's another issue.
