I don't think it's easy to destroy a small moving object so far away that you can barely see it. The UAV don't has to fly too close to take photos or video and it can be very small. A more useful thing for the criminals would be a jamming device against the wireless signals of the UAV, but then they can make the UAV work without wireless (without the live stream it can still take photos and videos of the place).
