Drones flying overhead

How much does it cost the tax payers to send those drones flying over head? How much does the fuel cost? Do they have more important tasks to tend to? lets talk about the predator outside the same young man that chased me right up to the back door of Catholic Charities a few months ago with the intent to do me bodily harm. He is sitting outside now. Your going to be there for a few hours and be careful I have a lot of stress built up. I will not go easily and I will not go quietly into the night sweet heart.
