In my opinion it allows the public to see Republicans for what they are during their questioning. It also gets it out of the horses mouth some of the things we all sort of believe anyway. It also makes it however much harder for dump and co to kill the Mueller investigation.

I suspect that the whole jail time thing is a smokescreen and that the prosecutors will give Cohn witness protection.

It just makes more sense. You can’t testify against the most powerful man in the world, who also happens to be useful to the second most powerful man in the world and expect to live openly.

I don’t think there is a prison anywhere that would be safe enough.

Post-sentencing reduction of a sentence is always a possibility if the person continues to cooperate with prosecutors. Whether that's his reason, or whether he is seeking revenge against Trump for discarding him after the election and later throwing him under the bus, or whether he is genuinely repentant is known only to him.

And annoys the maggot, its all good.
