Playing devil's advocate, what are the guaranteed abuses if drones are used in this context? You could certainly make a slippery slope argument, but at a huge event that is taking place in public there can be no assumption of privacy. Is a drone any different in this context than any other type of camera?
I am not sure I follow you on this one. It isn't like the type of technology used in drones can't be used in stationary cameras. A drone is simply a flying version making it ideal for short term deployments like surveillance on an annual sporting even like the Boston Marathon.
