Which circumstances is the government able to interfere with freedom of speech?

The government can interfere with freedom of speech in circumstances such as when speech incites violence, constitutes hate speech, or poses a clear and present danger to public safety. Additionally, restrictions may be imposed to protect national security, prevent harassment or defamation, and uphold public morals. Such limitations must be narrowly tailored and justified to ensure they do not excessively infringe on individual rights.
