One of the remarkable things about the U.S. constitution is that it theoretically allows no escape rope from protection of rights; by contrast the constitutions of many European democracies as well as Canada contain "notwithstanding clauses" that allow free rein to the government when they deem it necessary for any reason to trample on your rights.

Not saying the USA is particularly good about upholding those rights... pur government has been looking for loopholes in the Bill of Rights since it was ratified.
