The fix is not killing ICE officers.
The civil rights movements of the 60s, Jim Crow, etc, won by being willing to be beaten. By voluntarily entering a cafe and sitting there waiting to be served like a human being, meanwhile being willing to be called names, dropped food and drinks onto them, burnt with cigarettes, abused.
That willingness and perseverance in wanting to be recognised as the human beings they are awoke the rest of the population.
Pacifist demonstrations and matches are a way to achieve that. They are displays for your fellow colleagues, not for the government you want to depose. Make clear that they are pacifist. Prepare and inform the people going. Sit down if you are charged. Stop violent people there. Etc. Make obvious that the fascist are fascists that way and say and invigorate people to your side.
Heh, I was thinking the same, didn't know exactly when the day was. So maybe we indeed have something going on for ouselves.
