System-77 / Civil Counter-Reconnaissance offers military-style unmanned surveillance to activists, demonstrators, et al. I'm impressed (even moreso if it works), but for some reason not surprised - there's always a technical reaction on one side to the steps taken by the other - the same applies to, say, use of handweapons amongst the criminals and the police.
It's also a sign that the two sides are becoming more polarised, and as reasoned approaches give way to ideological polemics, the chances of any agreement being reached diminishes. Time to switch my "politics" hat for my "art of war" hat.
I've yet to see the demo footage, though.
