Is it illegal to say shut up to a cop?
It's generally not illegal to tell a cop to "shut up" because the First Amendment protects insulting or offensive speech towards police, but it's risky, as officers can escalate the situation and potentially arrest you for related charges like obstruction, disturbing the peace, or resisting arrest, especially if your words are deemed "fighting words" or incite violence, though courts interpret this narrowly for police, who are expected to show more restraint. While you have a right to speak freely, officers might interpret it as a challenge, leading to charges even if the speech itself isn't a crime.

Is it illegal to cuss out a cop?
It's generally not illegal to curse at a police officer in the U.S. because of First Amendment protections for free speech, but it can lead to arrest if the language crosses into "fighting words," threats, or disrupts public order, potentially resulting in charges like disorderly conduct or resisting arrest, depending on state laws and the officer's interpretation of the situation. While cursing alone is usually protected, actions like shaking fists, spitting, or making threats can remove that protection and lead to criminal charges.
