We had quite a show last week as the Seattle Police held a public meeting to discuss their plans to use small surveillance drones for various purposes. Protesters made the meeting pretty much useless - lots of loud concern over civil liberties. I fear the coverage of offensive weaponized drones combined with a general concern over past misbehaviors by the police here have caused people to be especially suspicious of both the technology and the motives of the department.
The city is planning on spending app. $80,000 for two devices (which seems outrageous to me, but then again, I suspect they are getting a really good warranty).
I believe the ones they are looking at are the Draganflyer units (http://www.draganfly.com/)
