Remember. When and if you start flying commercially there are no flights directly over people. The FAA won't start issuing those Part 107 waivers for a while. And flying over people is a trigger for FAA enforcement.
If you are flying recreationally it is still best to choose a flight path that does not place your UAV directly over people.
BTW. if you are applying for UAV insurance, one of the things that they may not agree to insure are weddings.
Fly safe.
