Last week’s massive No Kings protests demonstrated our massive new capacity, still largely untapped, for more strategic collective action against the emerging authoritarian order. This new capacity demands new ways of thinking and acting together. No longer do the usual players in public life have the stage to themselves. No longer can familiar routines of resistance suffice for this occasion.

Allow me to suggest three new arenas of opportunity — and burning need–for new forms of action.

First: the new flashpoint in resistance to mass deportations is our regional immigration courts. Never fully endowed with due process, already a broken part in our broken immigration system, these courts have been turned into traps for law-abiding legal residents. Most recently, they are traps for people denied their day in court by sudden executive action.

I have written elsewhere about the need for resistance on this front. Here in Northern California and elsewhere, this resistance to this perversion of justice already forced the temporary closure of regional immigration courts in San Francisco and Oakland. I suspect these developments will be used as a rationale for the extension of Trump’s military occupation of California to our region.

Second: again and again in our history, morally motivated “sanctuary” has taken new form in response to new circumstances. It is time to re-invent sanctuary again. I have also written previously about how as whole communities we can and should now exercise our 4th and 5th Amendment rights by establishing many new “4th and 5th Amendment sanctuary spaces.”

Any space not normally open to the public — including our homes, workplaces that are not open to the general public, parts and sometimes all of a church campus and even, in today’s new environment of school security, many school campuses — can and should be off limits to immigration enforcement agents in the absence, as is common, of judicial warrants.

So now, thousands of 4th and 5th Amendment sanctuary signs should be produced and distributed and displayed on thousands of doors in our communities.

In particular, faith communities are becoming more and more infused with the spirit of sanctuary. They can respond not only on church grounds, but also as members of congregations bring the sanctuary spirit into their own homes and workplaces.

And third: as the illegal military occupation of our communities begins to unfold, it is time for a new GI movement. Members of the U.S. military or National Guard are obligated to resist illegal and immoral orders, and we civilians are obligated to encourage and support them. As we veterans of the Vietnam era know well, there are many ways to do this: some consistent with the Uniform Code of Military Justice, some involving civil disobedience and some more surreptitious.

The many veterans in our emerging new network of resistance have a special ability to speak to young men and women that are deployed for illegal and immoral purposes in our communities. We have this ability not just because of the power of the veteran’s voice but also because, again and again since the Vietnam War, we too have faced deployments that demand resistance.

I am certain that there are and will be many other opportunities for new activities that respond to the unfolding challenges of the present and near future. So I hope these examples might help inspire many ways to deploy our new capacity for collective action.
