The Gaurdian has an excellent essay.

Because Americans like me were born in freedom, we have a hard time even considering that it is possible for us to become as unfree - domestically - as many other nations. Because we no longer learn much about our rights or our system of government - the task of being aware of the constitution has been outsourced from citizens' ownership to being the domain of professionals such as lawyers and professors - we scarcely recognise the checks and balances that the founders put in place, even as they are being systematically dismantled. Because we don't learn much about European history, the setting up of a department of "homeland" security - remember who else was keen on the word "homeland" - didn't raise the alarm bells it might have.

Antiwar has more:

America is headed for a military dictatorship – and recent legislation makes this all but inevitable. Last September, Congress passed the Defense Authorization Act, which empowered the president to declare martial law with very little provocation, namely in the aftermath of a "terrorist attack or incident." Having determined that "the execution of the laws" is hampered by the "incident," the president can unilaterally impose martial law – without the consent of Congress, which need only be informed of the event "as soon as practicable." The only condition attached instructs the president to report to Congress after 14 days, and every 14 days thereafter.
