I'm guessing that there is no apparent urgency because the overall terrorist threat level is currently low.One thing that disturbs me on drones and the lack of anyone much caring about them flying around like this. The tech is there for a drone attack by terrorists. Why does no one look at this as a possible problem? They could release a biological agent, etc. etc. If Amazon can use them to deliver packages....well, you get my drift here.
