I can't make up my mind if this is "movie plot threat" or not. Has it happened to other important figures before?

And can the prosecution be punished for this kind of behaviour?

Then again, I guess if you can shop around for (politically-appointed) judges, it wouldn't be too hard to find a judge to indulge some bullshit prosecution.
