These events and factors are not such that they are amenable to presentation in a courtroom. There is no "accused" or "defendant." There are few overt acts - merely abandonment of customary or required precautions. Hearings are the only way to bring this to light, with the body holding hearings having subpoena power and the ability to take testimony under oath, under penalty of perjury.
The truth will out.
Uh...60 lower court cases and 2 SC cases have already considered the "evidence"...and found it to be lacking. Hence all the dismissals. You don't get a do over just because your man lost. Sorry, doesn't work that way.
