How to push an agenda..!
This story is amazing for how useless the authorities seem to have been.
Anyone with any sense would have jammed the signal and just followed the drone home to whoever was controlling it, but they didn't - why?
I think this was an PR campaign for a black ops type company who were doing this to help the various useless agencies who can now lobby for more powers, and extra funding for equipment - its win / win all around!
