The scary thing about those blimps is that we used exactly those in our various warzones. Look for them in pictures of Kabul or Baghdad while Americans were there. I used to joke to buddies in my unit that it was even the same contractor sitting in the trailer where the blimp is anchored, watching the video.
Looks pretty conspicuous to me, and also extremely unlikely to be used for sustained surveillance of a person. Also sounds likely to be discontinued when funding runs out. A load of hot air, in other words.
