In the US. As I do more irl stuff, I am becoming concerned about being arrested at a protest or whatever. I've not yet come anywhere close to this happening, but should I do some prep like this ahead of time? Are there PSL approved lawyers or something, how should I know who to call? Will I need to have the number memorized? Can I cold call them post arrest or should I form a relationship first? I don't want to get billed.
