You can't know all the evidence. And the evidence you could know, but probably don't, isn't "weak".

Bragg wouldn't have brought this case if he wasn't sure he can get a conviction. And that's actually unfair treatment: With any other defendant he may take bigger chances, be less hesitant, less careful. And the case wouldn't have been derailed that long. Do you even know the whole history how this got deferred during the Trump presidency and even after?
