It is political theatre. Nobody of any importance is getting in trouble for Jan 6th and instead only the poors who attended are going to prison for the ideas of rich republicans.
That's exactly what this is. Donald Trump, Steve Bannon, Mo Brooks, and other big name Republicans will never be punished for Jan 6. The Iran-Contra precedent says the AG's office will generally assume those who did testify before the committee have immunity.
So how is it not?
