Interesting article conversely more to the post from Undisclosed1 is the editorial itself. It states "may soon find themselves". Just the fact that North Dakota is "quite progressive" in this pursuit suggest my theory, drones will play a role in security applications sooner than later. My poll here 77% voted yes, at least worth a conversation.
I met a guy here in Houston that builds specialized drones for video production companies. With all carbon fiber parts, twin rotors and gimbal mounted camera, it is a very high tech machine. He also can stream 480P video to his video glasses at speeds reaching 50MPH flying through trees. Why not let police use an aerial approach to crowd control, hostage situations, bomb threats?
Disbursement of chemicals, rubber bullets and or tasers not thus far, but it's coming to India. http://www.bbc.com/news/blogs-news-from-elsewhere-32202466
