The closest thing I can find to a proper poll on the drones thus far is the reader survey accompanying this article from the news aggregator Terra, the respondents to which were overwhelmingly in favor of the drone program, with 77.5 percent calling it a good idea. Of course, just 40 people have answered it, which limits the salience of the poll just a tad.
Also, evidently a woman filed a freedom of information request with the IFAI after seeing a drone in an independence day parade last year. The fact that they would throw these unusual vehicles serving as the foundation stone of a super-secret program into a public parade leaves me speechless. I guess they figured everyone would be too drunk or ignorant of modern weaponry to know what they were looking at, but they were wrong! The agency has announced that the Federal Police are obligated to turn over all info regarding the plan.
