Clear violation of this dude's rights. I don't know how you can see it otherwise.
If he's guilty, then securing a guilty verdict with a non shit person on the jury should be easy right?
The problem is they want to kill him. Another trial means he may be found not guilty or may not get the death sentence. Even if he is found guilty and gets the death penalty, it opens up all those other options for appeal and it mean the sentence is probably not carried out.
