You keep saying this.[Mueller] wants to put an American General in prison for nothing.
I assume you are referring to Lieutenant General Michael Flynn. Regarding prison, he has not been sentenced, so you don't actually know if Mueller will ask for that. And you claim it is "for nothing." He pleaded guilty to lying to the FBI. That is certainly not "nothing." Moreover, according to the Trump Administration, Flynn was fired for lying to VP Mike Pence about his conversations with the Russian ambassador about sanctions.
So the official story from the Trump Administration is that Flynn lied. The story from Mueller's team is that Flynn lied. That seems to indicate a pattern.
Lots of things are happening for him to be incompetent. We will see how this turns out.In short, he is incompetent.
