This is excellent news and I'm incredibly grateful the code used to convict people will be publicly scrutinized.
That said, me and other C# devs have already found numerous signs that at least parts of the codebase were done by someone clueless or inexperienced with C#. And there's no tests.
If someone spends the time to look into the codebase, I'm predicting a basically 100% chance that parts of this code will be shown to produce inaccurate or completely wrong results. Innocent people will probably go free because of this.
