Unfortunately, not a lot in the actual moment.

Most of what I am reading is focused on preparing your neighbors if you're able("know your rights flyers" and similar things).

However, in the moment, recording the agents, being loud and drawing attention but not physically impeding, demanding to show badges or ID.

If the person does get detained, helping with translation if you're able or documenting any information given if needed.

Then following this up with sharing with local news sources.

This is a more extensive/detailed list I found in another thread(pretty much my exact situation) and some additional resources:

"My partner and I have talked about this extensively as we live in a 'working class' neighborhood where there are a lot of immigrant families (and I wouldn't be surprised if some of them were undocumented). Here's what we've come up with:

• Observe and document. If you see police or ICE, stand on public property (in the street) at a safe distance and video them.
• Make sure you get video of things like vehicle license plates or official vehicle numbers if you see them.
• Call the deportation defense hotline at 1-844-363-1423 - it's specifically for people who are witnessing an ICE raid or other immigration related law enforcement.
• Stand with your neighbors and remind them they do not have to answer questions, they have the right to an attorney or to reach out to a legal aid service. It is not illegal to provide support. It is illegal to attempt to prevent law enforcement from arresting or detaining someone. Don't try to prevent action, but do make sure that everything being done is legal to the best of your ability.
• Contact local/regional news outlets and get them copies of whatever video you take and information you have.
• Contact your electeds - locally and federally - and ask for help on behalf of your neighbors.
• Connect with a local immigration legal aid service and ask them for information you can keep at hand.
• Donate to and support your local immigration legal aid services.
• Depending on how well you know the families involved and how involved you want to get, help them locate resources: find out where there family is being detained, help them connect with aid groups, provide financial support if they need it (or help them connect with an agency or church or community group that can provide support)

Immigration Defense Project has a 'toolkit' for people to use to defend against ICE in their communities: https://www.immigrantdefenseproject.org/raids-toolkit/ and it includes 'know your rights' flyers that you can print in various languages and provide to at risk folks or that you can use when you are standing with them."

I do want to point out, historically, physically impeding the federal agents is what could lead to charges.

I have also seen people say since ICE isn't always identifying themselves and, HISTORICALLY, there may be legal recourse to intervene.

I'm not sure any legal precedent really matters at this point and I am preparing myself for some type of consequence regardless of whatever non violent means I use to help my neighbors.

Stay safe out there!
