Free speech and your rights when posting online
What the First Amendment does and does not protect when you post online, and who it limits.
The 10-second version: say this
- I want to remain silent. I want a lawyer.
- I do not consent to a search of my phone.
Use these if police contact you about a post. Then stop talking.
Do
- Assume anything you post can become public.
- Screenshot posts and messages you may need later.
- Read an app's rules before relying on it.
Don't
- Don't post threats, even as a joke.
- Don't delete posts after police contact you.
- Don't explain a post to police without a lawyer.
Myth check: "Free speech means no one can remove my post"
The First Amendment limits the government. It does not limit private companies. This means:
- An app can remove your post or ban your account. That is not a First Amendment violation.
- A private employer can usually discipline you for a post. Some federal and state laws protect some posts, like talking with coworkers about pay.
- A private school can usually punish you under its own rules.
The government, including police, public schools, and public officials, is limited by the First Amendment.
What the First Amendment does not protect
Most speech is protected, even speech that is rude or unpopular. Some kinds are not:
- True threats. A true threat is a serious statement that you mean to commit violence against someone. In Counterman v. Colorado (2023), the Court said the government must prove at least recklessness. That means the speaker consciously ignored a substantial risk the words would be seen as threatening violence.
- Inciting violence. Speech meant to cause, and likely to cause, immediate illegal action.
- Defamation. False statements of fact that harm someone's reputation.
- Harassment and stalking that target a specific person.
- Fraud, and speech that is part of committing a crime.
"I was joking" does not always protect you. Police and schools may still investigate.
When a public official blocks you
- A public official is someone who works for the government, like a mayor or city council member.
- In Lindke v. Freed (2024), the Court gave a two-part test. Blocking you can violate the First Amendment if the official:
- Had real authority to speak for the government on that topic, and
- Was using that authority in the posts you were blocked from.
- If the account is personal, blocking you is usually allowed.
School punishment for posts
- In Mahanoy Area School District v. B.L. (2021), the Court said a public school could not punish a student for a vulgar weekend Snapchat post made off campus.
- Schools have less power over off-campus posts. They may still act on threats, bullying, or harassment.
Your posts as evidence
- Public posts can be used as evidence in court.
- Police generally need a warrant to search your phone.
- Police can sometimes get records from apps with a court order or warrant.
- Deleting posts after you learn of an investigation can be a separate crime.
Common questions
Is it illegal to post threats online?
Yes, true threats are not protected speech. A true threat is a serious statement that you intend to commit violence against someone. In Counterman v. Colorado (2023), the Supreme Court said the government must prove at least recklessness about how the words would be seen. "I was joking" does not always protect you.
Can I get fired for a social media post?
Often, yes, at a private job. The First Amendment limits the government, not private employers. Some laws protect some posts, like talking with coworkers about pay. A few states protect legal off-duty activity. Government workers have some First Amendment protection.
Can a government official block me on social media?
It depends. In Lindke v. Freed (2024), the Supreme Court said blocking can violate the First Amendment if the official had real authority to speak for the government on that topic and was using it in those posts. If the account is personal, blocking is usually allowed.
Does free speech apply to social media apps?
Generally, no. The First Amendment limits the government, not private companies. An app can remove your post or ban your account without violating the First Amendment. Government officials and agencies are still limited by it when they act for the government online.
Can police use my social media posts?
Yes. Public posts can be used as evidence in court. Police can sometimes get records from apps with a court order or warrant. Police generally need a warrant to search your phone itself.
Is it illegal to delete posts during an investigation?
It can be. Deleting posts after you learn of an investigation can be a separate crime. If police contact you about a post, you can say: "I want to remain silent. I want a lawyer." Then stop talking.
