These are called petit juries and it's imperative that they believe that the accused is innocent. This is not the case any longer. The judge won't tell them that their duty is to try the law even though he would have to admit that it is true. If they are shown in the trial or otherwise that the law is not constitutional, they have an honest duty to throw out the law and declare the accused to be innocent. The Fifth Amendment guarantees that our Government cannot take life, liberty or property from any person without due process of law.
Due process begins with the Constitution.
Once the commands in the document are ignored, due process vanishes. Claims that the 'necessary and proper' clause of the constitution gives the federales the right to prosecute all crime is nonsense. The clause applies only to powers granted in the document and is verified by Hamilton. We have to demand Congress end this charade. They are the creeps who passed this legislation and have to be the ones we must go after.
