It's more effective in an area where police's response to a perceived threat (real or imaginary) is to shoot first, perspire later.

Not to take anything away from this particular instance. It's rad and inspiring as hell. However, I fear that, were I to try this at any protest in my area, I would be forcibly aerated in short order.

Could be doomerism has a hold on me this afternoon, but, if anything, this post makes me despair that any effective protest in my country (i.e. something with enough teeth to make oligarchs take notice) will be met with deadly force employed in the name of "restoring order", and the whole political and media apparatus will jump through hoops to frame the story as, "well, we all applaud protestors for making their voices heard, but they didn't follow our clear directions, and therefore they brought their fates upon themselves."
