Final answer:
Society can intervene with freedom of expression and speech to protect public safety, prevent harm, and in cases of national security or international conflict.
Step-by-step explanation:
The government may intervene with freedom of expression and speech in certain circumstances when it is necessary to protect public safety or prevent harm to individuals or society. One example is when an individual makes a direct threat to someone's safety, such as stating they will kill a candidate at a specific time. This crosses the line from protected speech to a threat and can be punished by law.
Another example is when speech incites immediate violence or poses a clear and present danger. For instance, falsely shouting fire in a crowded theater and causing a panic would not be protected by freedom of speech because it endangers public safety.
In cases of national security or during times of international conflict, the government may also restrict certain types of speech that could harm the nation, its people, or its military forces. However, these restrictions must be carefully balanced with the constitutional right to freedom of expression.
