You don't need absolute proof to put someone on trial, or to investigate.
That's WHY we investigate, to establish if there's been wrongdoing. And that's why we put people on trial. To determine guilt.
If you were required to be determined guilty before we could investigate, nobody could be investigated. Because it'd mean we would need to investigate to find the evidence to allow us to investigate. A catch 22.
So I reject the suggestion that the evidence needs to be any good at all. It can be crap. All its gotta be is enough to investigate to actually find out properly if there has been wrong going. And we've long past that point. For the whole freaken lot of them.
If you want we can find out wtf the clintons were doing on epsteins plane at the same time.
And no, rich people go to prison all the time.. It's just that they go to a separate rich people prison version of prison
