1) that's an absurd proposal, would be very expensive, and incredibly dangerous if it malfunctioned. Imagine it detects a car or airplane as a projectile and starts shooting at it. 2) drones don't make anything new possible. They could just as easily use homemade rockets, mortars, old fashioned RC planes, etc. I don't know why people are so afraid of possible abuses of new technology. There are so many old technologies which are also abusable in similar ways, but we don't generally worry about it because it's just not a significant problem.
