I don't know if our arrangement with the SDPD allows for it, but
this (tl;dr "small groups of 4-10 are effective") seems a great idea. After the protest and I was wandering around alone (like an idiot) following the track to the Fifth Street station, people actually came up to me and asked what was going on.
More particularly in our case: mass protest to get visible. March around the gaslamp, again for visibility's sake. Break off into "task forces" wandering about high-traffic areas just hitting the grass-roots.
Issue: command, control, communications. Perhaps each group should have a designated 'radioman' who checks in with the partyvan at determined intervals via texting? Risks namefagging, especially should cel phone contact lists get out, but would prevent the main group from moving on and leaving task forces out in the cold.
Issue: bullbaiting. Smaller groups may invite this tactic to actually be used. Four to ten people are still capable of self-regulation, however, and if we're being decent and the skin jobs are being assholes... well... yet another point to us. Non-issue.
Issue: SDPD not being able to keep an eye on all of us at all times. Safety argument: if they're watching the main group of people with masks, that protects us from Scientology using all the masks it bought up to rob liquor stores throughout the area as we're disassociated from such pettifoggery. Possible dealbreaker--but could be ameliorated by using predetermined routes/areas of operation that we share openly with the SDPD, along with the Air Raid/Duck And Cover protocol.
