I understand that some police forces are starting trials with unmanned aerial `drones` like the military use in Iraq and Afghanistan. These can be `piloted` from a control room many, sometimes thousands, of miles from the scene under observation. I have found a good example of how these can be of tremendous use to those `on the ground`. I can think of a few times I wish I could have called in one of these. I wonder if they can drop "Policing Pledge" leaflets?
