IMHO and that is all it is... Roger Stone is a dirtbag that probable did get caught doing stuff... Now the fact that the investigation was probable crooked, the means they used to get evidence was probable illegal, and that the jury and judge was crooked means the criminal system in the US is just a freaking mess. I wouldn't want to be given a trial within 200 miles of DC.
That said, I really don't know the right outcome, but chicken or egg, if the means to obtain the info against Stone was illegal... he probable should walk (and I hope he falls in a hole big enough to drown him). Did I mention I didn't care for him or his type.
