Blueberry,   I do not need to be on council to answer your question number 4 with "Yes", and number 5 with, "There are many reasons to trust our local police, beginning with the facts that they are local and so directly answerable to us, that they have a track record of respect for the rights of our citizens, and that there is no pragmatic reason to believe that the use of UAVs will infringe our privacy and freedom."   And yet, though these answers are objectively and demonstrably true, I do not expect you to find them satisfactory.   And while government has killed more person in history than all of the criminals of the world combined, so has fire.    But we humans derive net benefit from both, when used properly, and there is no reason to believe the use UAVs is any different.
