No third-party witness should ever respond to any kind of discovery or other legal process without first obtaining the assistance of competent counsel.
You know what that’s called? It’s called a felony. And you know what can be done about it? Go to fucking court and prove it. The mere possibility that a defendant might suborn perjury or intimidate witnesses or whatever in no way justifies a blanket ban on public disclosure of discovery products.
To the point that people lose their goddamn minds when the criminal defendant is somebody they hate. The First Amendment protects Steve Bannon’s speech just as much as anybody else’s.
Get a goddamn lawyer. Don’t be an idiot. There are substantial downsides if you fuck things up because you’re doing it on your own. Even if you’re testifying for the prosecution in a criminal trial, the mere fact that you have engaged counsel will make your life much more pleasant because every lawyer on the case will have to go through your lawyer instead of pestering you in person. And frankly, if you’re testifying in a criminal case, there’s a pretty decent chance you’ve got criminal exposure too.
Don’t be an idiot. Lawyer up.
