“Evidence of innocence” is a very problematic concept. Have you thought through what is your evidence of your innocence? (Not just regarding to this case, but regarding all cases involving dead or missing people.) Should we execute you if you ever come up short?
Conviction requires proof beyond a reasonable doubt — all the onus is on the prosecution to prove that you indisputably committed that crime. In this case unreliable evidence was used without which this standard likely would not have been met.
Once you’ve been convicted (in this case on shoddy evidence) the onus is on you to offer evidence that you’re actually innocent - a reasonable doubt is no longer sufficient, you need to offer strong, new evidence that disproves the already decided “fact” that you committed the crime.
The standard before your convicted is that the jury must find you guilty beyond a reasonable doubt. The standard after you've been convicted is that you must have found substantial new evidence that warrants reconsidering the verdict, or you must show that the original trial was mishandled somehow. "I think the jury was stupid" is not a valid appeal.
I think this re-raises the "trap door" question.
In this case, up until conviction you are presumed innocent and guilt must be proven. Post conviction most of the appeals process is bared if not filed within 14 days of conviction (it used to be forever but then the US Justice system decided woohhh there that's too long and burdensome on the Justice system so 14 days was deemed a reasonable change to the previous 'forever'. A totally reasonable happy middle). After 14 days from conviction really the only relief available is to prove actual innocence, a much higher and more difficult standard to meet.
With the caveat that this is coming from someone with zero training in law: what a load of horseshit.
