I wonder how much information one mesh node could accumulate to incriminate other participants? How many of "the people" will be willing to participate in an uprising like this if they know that a government stooge is likely no more than two or three hops away?
You do realize that most of these protesters are literally standing two or three steps away from a government stooge wearing riot gear, right? It's not like they're even trying to blend in.
I think we're forgetting our history here. Peaceful protest only works if it seriously inconveniences as many people as possible for as long as necessary. Politely camping in a park without a permit doesn't really cut it. If they're using tear gas on you, it's a start. If they're using water cannon on you, you're getting somewhere. If they're setting dogs on you and hauling you away to county lockup by the busload, you're doing it right.
People forget exactly what happened during the Civil Rights movement in the United States. It's peaceful protest only on the protester's side. On the side of the so-called civil authorities, it's decidedly not peaceful, and rarely civil. And this has to go on for quite a long time. Literally years.
Occupy Wall Street accomplished nothing because none of that happened. These protests in Hong Kong will likely accomplish just as little. They're carefully avoiding inconveniencing anyone. Nothing happens if you do that. We demonstrated exactly that in the US. Hong Kong should learn from our mistakes. If they want to actually change things, they have to get obnoxious and get hauled away by those riot gear-equipped policemen. In droves. By the thousands. Or since we're talking about Chinese numbers here, by the tens of thousands. (It takes some serious effort to match per capita numbers in China.) Being careful not to interfere means you can be ignored, not just by authority, but by the man on the street as well. You must inconvenience people. You must interfere. You must do so as peacefully as possible, but you must do so.
Most recently, the US did it wrong. We in the US weren't willing to pay the price to get the oligarchs to back down. The populations of several Arab states did it right. Yeah, it hurts. Sorry, but that's what it takes. Are you in China ready?
