Well, first I can almost guarantee that the surveillance tech being employed on a predator drone is substantially more advanced and wide ranging than a simple human operated video camera, but I also don't think it's a good idea to have guys with video cameras in helicopters recording protests either unless it's to film illegality. It has a chilling effect on the exercise of free speech. Peaceful protesters really shouldn't be getting surveiled / data gathered during protests shouldn't be getting mined, and unless authorities can guarantee that isn't happening then recording makes me uncomfortable.
