I have fkown journalists from as far back as the 1950s who employed cameras that looked like anything but cameras. Tesssina cameras in a cigarettte box, to photograph vice in Mexican border towns for example. The old one-shot camera strapped to the leg to photograph a woman's execution in New York. There are many instances where a journalist will get beaten up, arrested, killed or all of the above for merely showing a camera. It is a mean world. I am sure many more clever gizmos will be employed. When private business and the government conspire to make it a crime to report torture of animals -- or people -- something creative has to be done no matter if it's glasses or drones. You don't have to let the creeps win.
