You are seemingly not understanding how this political motivated prosecution works. It works exactly like this.
"Show me the man and I will show you the crime."
You still have the right to let the man know your opinion. If my man was being mistreated and done wrong as you obviously believe, I would let my opinion be known.
In Court, when an Attorney strongly disagrees with a ruling by the Judge, he addresses the Judge thusly: Your Honor, I strongly disagree with your ruling. I intend to appeal it to the next level. Or, Your Honor, I take issue with your ruling, I intend to take it to the next level.
