and in this case the evidence is hard to come by.

Russel Brand has been doing good work pulling up info on the Lab Leak theory.
Hes been doing good research on the topic and since hes not someone that aligns himself with the left or right on the political spectrum he might be a good unbiased point of legitimacy for such research.

the court systems are heavily corrupted

Yes courts are corrupt. But when it comes to the court in cases like this, a very strong public response would overrule any monetary payment a judge or judiciary system bureaucrats would receive.

At some point people need to 'man up' and take things into their own hands

I dont think thats the answer. Its about gathering evidence and piling it on top of each other. If it indeed did leak from a lab, and my personal belief is that it did, all that is required is a match to light the keg. I have the same data to go from as you do but Im still not ready to claim with certainty that the lab leak is a fact... We need consensus and more info. And im not talking about facebook fact checker gimps.

Its going to be a famous TV personality, it could be Joe Rogan, it might even be CNN that breaks the news. It just takes 1 moment and pulling a single piece of evidence for the board to flip..
Its never about just the facts, its about if those facts will be generally accepted.
