This individual lays out a lot of the details of the situation and facts of the courtroom for our review.
Upfront, although not double jeopardy, this is very much a case of extreme federal leveraging of pressure on the Hammond family and a case of using anti-terrorism laws to unduly punish American citizens for common and necessary private ranching practices.
The original sentencing, by the now retired judge, was a very fair and informed sentence. The second sentence is clearly a case of using the laws on private ranchers and citizens in order to add undue pressure and personal struggle to the family.
This is a situation of broad overarching Federal Laws being applied in a situation and locality they are not suited to.
Please watch, read, and learn as much as you can about this situation.
