The Constitution does refer to citizens and persons in different contexts. Thus you're saying that all of times "persons" are referenced really means "citizens."
The founding fathers certainly were not haphazard with their wording.
Optical tech could make people, aircraft invisible

coondoggie writes "So you thought only Romulans had a cloaking device? Hardly. Purdue researchers using nanotechnology this week have taken a step toward creating an optical cloaking device that could make objects invisible. "How to create a design that works for all colors of visible light at the same time will be a big technical challenge, but we believe it's possible," he said. "It is clearly doable. In principle, this cloak could be arbitrarily large, as large as a person or an aircraft." Two requirements are needed to render an object invisible: Light must not reflect off of the object, and the light must bend around the object so that people would see only the background and not the cloaked object itself, according to researchers.
