Jail and Court Solidarity use different tactics but with the same end goal in mind - taking care of each other. They can be used separately but are most effective when used together. A typical Legal Solidarity timeline looks like this:
A group of activists gets arrested. They begin using Jail Solidarity by refusing to give their names and by using physical non-cooperation to keep people together and safe.
The activists begin using Court Solidarity by having the legal team communicate the proposed demands and the Court Solidarity tactics (pleading not guilty, demanding a jury trial, etc.) to the prosecutor.
The prosecutor agrees to negotiate - OR -
After a few days, it becomes clear that Jail Solidarity isn't being effective, or people are unable to stay in jail any longer. The activists decide to give their names and leave jail as a strong group rather than a weak trickle. Jail Solidarity is now over and all efforts are focused on Court Solidarity.
