Some record audio, too, but know the laws in your state about recording conversations.
I googled what to do if ICE shows up near you & you're a US citizen & here's the AI overview.
=========
If you witness Immigration and Customs Enforcement (ICE) activity involving someone else, you can act as a legal observer, document the incident, and assert that the person has a right to remain silent. Never physically interfere with the agents, as this could result in your arrest and endanger others.
Document and observe from a safe distance
>> Keep a safe, visible distance. You have the right to observe and record law enforcement activity in public spaces, but you must not interfere. This includes following any orders from agents to step back for safety reasons. Stay far enough away that officers do not perceive you as a threat.
>> Record the interaction. Use your phone or camera to record the incident. Filming visibly is recommended. Capture details such as:
The names, badges, and vehicles of the agents involved.
The time and location.
Any conversations you can hear.
The context of the detention, including any street signs or landmarks.
Narrate and secure your footage. If possible, narrate the details you are observing in the recording. Once you finish, secure the footage by backing it up to encrypted cloud storage.
Remind others of their rights.
>> Announce the person's rights. You can loudly state that the person being questioned has the right to remain silent and does not have to answer questions about their immigration status.
>> Never give legal advice. You can inform people of their rights, but do not pretend to be a lawyer or offer legal advice. Instead, you can provide the phone number of a rapid response network or an immigration lawyer.
What to do if ICE is at someone's door. If ICE is at a neighbor's door, you can help by calmly and clearly asserting their rights from a safe, legal distance.
>> Remind them not to open the door. Shout to the person inside that they do not have to open the door unless the agents have a valid judicial warrant signed by a judge.
>> Distinguish warrants. Most ICE warrants are administrative, signed by an ICE official, and do not grant them authority to enter a home without consent. A valid judicial warrant must be issued and signed by a court judge.
>> Document and notify. Record the interaction and alert your local rapid response network or immigration defense organizations.
What not to do
>> Do not physically interfere. Never physically obstruct, touch, or resist an agent. Doing so can lead to your own arrest and may endanger others.
>> Do not lie. Providing false information to agents can have serious consequences. It is safer to remain silent.
>> Avoid posting sensitive information. Be cautious about livestreaming or posting identifying photos on social media, as it can expose the identities of vulnerable individuals.
Follow up after the incident.
>> Contact legal support. Notify your local rapid response network or an immigrant rights organization to report the incident and share your video and notes. They can help track the person who was detained.
>> Check the ICE detainee locator. If you know the person's name, you can use ICE's online detainee locator to help their family find them.
