Now the protesters are fighting back with their own surveillance drone.Tim Pool, an Occupy Wall Street protester, has acquired a Parrot AR drone he amusingly calls the “occucopter”. It is a lightweight four-rotor helicopter that you can buy cheaply on Amazon and control with your iPhone. It has an onboard camera so that you can view everything on your phone that it points at. Pool has modified the software to stream live video to the internet so that we can watch the action as it unfolds.
