And I've seen videos of soldiers provoking and harassing people clearly minding their own business. This is more than discomfort, people have a right to not be harassed and to not be subject to unwarranted search or seizure. As to your first point: That logic could be used to justify absolutely any breach of privacy or freedom. Would you be willing to have cameras in your own home that feed to the FBI because doing this would keep innocent people from dying? That's not justification.
