There is enough reasonable doubt to get at least a retrial for Mitchell. No one needs to prove his innocence on forums it is enough to show that there is evidence that he might indeed be innocence. The court is the place to prove innocence.
I agree about the retrial, I believe one day it will all come out that Luke really did it. Most other "suspects" have alibi's, no motive whatsover, all behaved as expected at the time. Luke stood out for a reason, and his alibi turned out to be an absolute shambles.
Your little brother finding his girlfriends dead body would make a night pretty memorable, yet Shane completely forgot Luke came home and burned his dinner, but he never forgot he was up in his room masturbating (which has been confirmed with internet history logs )
my problem with Lukes supporters is that they refuse to admit there is even a slight chance he could have done it, they are all in denial. It's very possible he done it yet nugnug even in this thread states his opinion as fact that Luke is innocent.
