“It's a free country.” “I have freedom of speech.” “He's innocent until proven guilty.” Does the US Constitution actually mention any of this using those words? In some cases, yes. Find out more in this neat Web page: Things That Are Not In The US Constitition.
One fun tidbit is the phrase “from each according to his ability, to each according to his needs.” A 2002 Columbia University study found that 2/3 of people thought it's part of the US Constitution when in fact it's probably the most famous quote from Karl Marx!
Another item that we've often discussed here at LIA – and indeed all bloggers deal with the issue – is “freedom of speech.” Often during a heated exchange, one commenter will declare that “I have freedom of speech” and go on to explain that any attempts to regulate blog comment infringes on that freedom. However….
The Constitution does protect the freedom of speech of every citizen, and even of non-citizens — but only from restriction by the Congress (and, by virtue of the 14th Amendment, by state legislatures, too). There are plenty of other places where you could speak but where speech can and is suppressed. For example, freedom of speech can be and often is restricted in a work place, for example: employers can restrict your right to speak in the work place about politics, about religion, about legal issues, even about Desperate Housewives. The same restrictions that apply to the government do not apply to private persons, employers, or establishments. For another example, the government could not prohibit the sale of any newspaper lest it breech the freedom of the press. No newsstand, however, must carry every paper against its owners' wishes.
Other interesting entries discuss issues like “executive privilege,” “taxation without representation,” political parties and primaries, and more.
It's an interesting resource because the discussion offers a good deal of historical perspective and information resources.
