Nice to find you again! I miss your comments with a lot of relevant citations.

What habits are useful to practice and what tools are useful to use to facilitate communication without getting nonviolent, peaceful, legal protesters in trouble just because they are trying to organize to express dissent?

I'll repeat my old recommendation: Assume three letters agencies can read all your communication anyway. Beware of the guy that wants to escalate and blow up everything, he is probably an informant (or an idiot).
