(CNN)Every American has the right to demonstrate peacefully. It's right there in the First Amendment. But it's not as simple as showing up with a sign.

There are some measures officials can use to limit protests, and it's easy to accidentally tiptoe into legally murky territory if you don't know the specifics.
So before you go, read up.

What are my rights as a protester? Where can and can't I protest? Can police or local leaders tell us to disperse? What can I record? Someone took a picture of my face at a public protest. Is that allowed? What should I pack to stay safe at a protest? What can -- and can't -- police do during a protest? What can I do if a police officer stops me? What can I do if I get arrested? What can I do if I feel law enforcement or other officials violated my rights? Can my workplace fire me if they find out I attended a protest?

1. What are my rights as a protester?

The First Amendment gives Americans the right to assemble peacefully and air our grievances. Historically, we've relied on protests to hold power to account -- think the March on Washington in 1963 for civil rights or the March for Our Lives demonstration in 2018 for gun control.
The government can't stop you from peacefully protesting, but they can impose some restrictions on the time, place and manner of the protest -- for example, barring protesters from walking onto a public highway or instituting a curfew that affects when protests end, Sykes said.
They can't block a protest simply because of its content, though.
If protests are planned in advance, organizers may obtain a permit so law enforcement can block off public spaces for them to demonstrate, Sykes said.
There are protections, though, for "spontaneous protests" that spawn in response to current events, like the protests that spawned after George Floyd's death, he said.
The First Amendment does not continue to protect protests that escalate to violence or the destruction of private or public property, he said.
That's when law enforcement has the obligation to respond and deescalate threats of violence, he said.

2. Where can and can't I protest?

A slew of public spaces are OK for protests -- sidewalks, city parks, streets and other public forums are usually lawful, Sykes said.
Some states require you file a permit to block off streets, and the right to assembly doesn't give you the automatic right to march on a public highway, Zick said.
People can be arrested or cited for blocking passage, he said.
On private property, you don't have the right to assemble.
Zick called it the "no man's land" in terms of the First Amendment, and police can move you off the property and keep you from demonstrating there.
They may even have that right to move you even if you're on public property. Special rules apply to government buildings because protests may disrupt business going on inside, Sykes said.
If the protest was permitted, you should be allowed to stay where you are -- but leaving the permitted protest site may unintentionally lead you into prohibited places, he said.

3. Can police or local leaders tell us to disperse?

It depends, Sykes said: If a mayor pleads with people to go home, you have no legal obligation to comply.
But police and local government can order you to leave, say, if they've imposed a curfew, as long as they give you ample notice to leave safely, Sykes said.
If you stay on the street past a curfew -- or if you protest on private property -- you may be cited or arrested.

4. What can I record?

You have the right to take photos and videos of what's happening at a protest in a public place, and you can record police, too.
Different states have different rules about audio recording and sharing that without the consent of the people whose voices you recorded, but the visual portion of videos and photos are always protected by the First Amendment, Sykes said.
If you're interfering with legitimate police operations, they can ask you to move. It's best to videotape them from a safe distance.
Police can't ask you to give them your phone or forcibly confiscate it without a search warrant, which they would've needed to obtain from a judge, he said.
If they demand your phone, though, comply to avoid escalating the confrontation. Afterward, you can file a police misconduct complaint or contact the ACLU, he said.

5. Someone took a picture of my face at a public protest. Is that allowed?

At a public protest in the United States, you consent to a photo just by being there. Anyone who photographs you protesting in a public place may have a right to use your image, and you may see images of yourself in the media or online, Zick said.

6. What should I pack to stay safe at a protest?

Pack light, Sykes said. He suggests you bring water and a snack at minimum. If you bring a bag, prepare for it to be searched.
In a pandemic, wearing a mask can keep you from breathing in droplets containing coronavirus. Coming within close contact of other protesters could expose you to their spit or sneezes, which may carry the coronavirus.
And if you fear you'll be arrested and will need legal help, memorize or write on your arm the number to a local or national law organization that could assist you in getting out of jail and handling your case afterward, Sykes said.

7. What can -- and can't -- police do during a protest?

It's the responsibility of police to protect your right to peaceful assembly.
They're also empowered to uphold law and order, which gives them broad authority to deescalate threats of violence how they see fit.
How they deescalate that violence depends on local laws and the circumstances under which they use them, which can be difficult to prove in court if you believe they used force unlawfully, Zick said.
Like Sykes said, police do not have the right to search your phone or personal devices without a warrant, which only a judge can grant them.
They also don't have permission to delete content from your phone, so if they tell you to delete a video you took or delete it themselves, they're in the wrong, he said.

8. What can I do if a police officer stops me?

Stay calm. Don't resist.
Ask them if you're free to go after speaking with them, Sykes said.
If they say yes, calmly walk away and rejoin the protest if it's safe to.
If they say no, and they detain you, don't resist and keep calm, Sykes said. Ask them what crime you're suspected of committing.
