which presupposes that everyone is a criminal.
Such is the slippery slope of authoritarianism, and why I'm against it.
Per your points: Our government has shown in no uncertain terms that it doesn't like us very much, if at all. So the fact that they offer more progressively narrow viewpoints is no big surprise, but that still doesn't make it right, or constitutional.
* Fourth Amendment – Protection from unreasonable search and seizure.
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
* Fifth Amendment – due process, double jeopardy, self-incrimination, eminent domain.
No person shall be held to answer for any capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.
What we've seen over the years is a continued narrowing over what contitutes "unreasonable" and "probable cause." These two ambiguous terms have been the hinge pins allowing our descent into a police state. "Secure in their persons...," though, is pretty straight forward.
So in the sense of the police state that has taken taken root in our once free society, you are correct. In the spirit of the Constitution, though, I must maintain my original premise.
