But wouldn't the fact that trials might be favoring conviction (I'm not saying they do, but just as a hypothesis) also drastically change the outcome of those non-trial cases (mainly plea bargains, I guess)? If I expect to be convicted, I'm more likely to agree to a worse plea bargain.
That might be true but it was not my point. I was merely arguing that not seeing many cases actually go to trial is not an argument that can be made in this case.
