I'd just like to say I think in general the concerns about civil rights being put at risk by blanket surveilance are probably worthwhile to consider.
That being said, I think drones can be used effectively in a number of situations especially in a state like California. Monitoring emergency situations such as forest fires, earthquakes and other natural disasters. Search and Rescue. And even monitoring of game hunting and public lands for poaching / pot farming ( this is usually done by ultralight flights and can be risky to the personell on board ).
I think in general a healthy skepticism is a good thing, but I also think drones can serve to better the general welfare of the populace if limited in their application. So I am glad that this is a route people are choosing to take. As always though, the devil is in the details.
