Don't you need to reveal the facts in criminal court? Right to see the evidence against you and all that.
Also, if the information would not exculpate the defendant, and the prosecution won't introduce it at trial as evidence of guilt, then the information can be withheld.
But I should mention the bad guys are trying to get grand jury assembled that would prosecute James Comey. Does that count as 'criminal trial process'? https://www.nytimes.com/2025/09/24/us/politics/james-comey-i...
I'm not a lawyer, but this corruption will be getting worse. That distinct is relevant still but for how long?
Now that Comey's been indicted, the trial process will begin, assuming he doesn't plea out (and I don't think he will). The uphill battle for the prosecution now begins.
