A relatively quick study of American history shows the U.S. Army did not Mirandize captured Confederates, nor give them Constitutional rights. If they could have exterminated us all, they would have, it was a war. Once we departed from the USA and became the CSA, we did not expect to be provided US Constitutional rights, nor did any idiot of the time suggest such a thing.
As I said, our Founding Fathers big mistake was assuming there would never be idiots in large numbers, as they are today. They should have probably spent more time explaining the foundational reason and purpose of the Constitution, and the importance of protecting it at any and all costs against enemies foreign and domestic. Maybe they should have put big red letters at the top... This does not apply to those who seek to destroy us! ....did they have red ink back then? I'm not sure! Don't think they needed it, because we didn't have so many STUPID people, who required big bold RED letters to understand a simple common sense point!
There is a huge difference between POWs and people arrested in the U.S. by law enforcement. No, if a U.S. soldier captures a combatant, or even if a soldier captures a foreign national in a combat zone as a suspected combatant, then miranda rules do not apply. That is pretty much a given, and your Civil War example is exactly that" combatants under military conditions.
But the AG is talking about NOT paying attention to our rights when a person is ARRESTED by LAW ENFORCEMENT. No military involved, yet if they label you a terrorist, out go the rights. That is wrong, no matter what dough headed fuck up says it's OK.
The 14th Amendment SPECIFICALLY STATES that the rights of a U.S. person - that means ANY PERSON residing in the United States - cannot have their rights removed EXCEPT THROUGH DUE PROCESS.
nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
To declare a person a terrorist to whom Constitutional protections do not apply, the person has to either be captured under military conditions (ie: captured by military personnel as an enemy combatant or suspected enemy combatant in a military combat zone) OR, if arrested by law enforcement in the United States proper or associated territories, due process must be applied. But for due process to apply, the legal system has to arrest you,
MIRANDIZE YOU because your rights are still intact until the due process procedure is over,, put you on trial, CONVICT YOU and SENTENCE YOU, with part of said sentence being the removal of your rights. Then and ONLY then can they DENY your rights and proceed to treat you as an enemy agent.
Anything less is pissing on the Constitution. It does not MATTER what "justification" you want to use. You piss on the Constitution, you will get urinated on yourself, eventually, as the "exceptions" are granted ever widened definitions. If the AG's policy is allowed to stand, all they have to do to remove ALL your Constitutional protections is declare you a suspected terrorist. They do not even have a defined policy for what it takes to SUSPECT a terrorist. Just say so, and you're a terrorist with no Constitution. Then they do whatever the fuck they want, and, if you're EXTREMELY LUCKY in the end, get released many years later with a "oops, guess you're not a terrorist after all".
