That's true about the hot tub. We already have helicopters but I can appreciate there's room for the drones to be more pervasive because of their lower cost. Holding police to standards isn't easy. We ask people to go out and pull long shifts, to react in complex and life and death situations both for themselves and for the public in a split second, should we hold them to a high standard? yes, should we give them a break for split second mistakes bearing in mind what we're asking them to do - also yes.
