I've been afraid of this for years.

I guarantee you that there exist (or will exist) highly profitable consultancies which specialize in faking evidence. Just think about how easy it would be to launder a million here, a million there, disguised as legal fees in some of these large cases.

We're approaching the limits of the traditional legal system with human juries. I don't how to solve this in the long term. I'll speculate that the solution will involve blockchains and a new, more minimal, totally decentralized legal system.
