What constitutional issues were raised by federal government policies during the war?

Answer is:

The issues were raised by federal government policies during the war are as follows:

limited speech when speech constituted a "clear and present danger"

Explanation:

Clear and present danger was a doctrine adopted by the Supreme Court of the United States to determine under what circumstances limits can be placed on First Amendment freedoms of speech, press, or assembly. The test was replaced in 1969 with Brandenburg v Ohios "imminent lawless action" test.

Example:

Although the U.S. Constitution's First Amendment protects freedom of speech, any speech that poses a "clear and present danger" to the public or government loses this protection. The classic example is that shouting "Fire!" in a crowded theater is not protected speech.
