I was looking up Sherar v. Cullen, 486 F. 945 and located this PDF document. It reads among a large number of other cases that coincide with Constitutional case law. Sherar v. Cullen is in this PDF and pretty much states there isn't any further need to list all the cases by saying:

Sherer v. Cullen , 481 F 946.

We could go on, quoting court decision after court decision,however, the Constitution itself answers our question � Can a government legally put restrictions on the rights of the American people at anytime, for any reason? The answer is found in Article Six of the U.S. Constitution: Miranda v. Arizona, 384 U.S. 426, 491; 86 S. Ct. 1603 "Where rights secured by the Constitution are involved, there can be no 'rule making' or legislation which would abrogate them."
