I love drones but I would not fly in cities or above a parade.
I pity the pilot and the lady, but flying in cities with lots of wifi transmitters/routers, not to mention cellphone towers, is asking for trouble.
This is that 2015 parade, based on YouTube.

Since the parade is on a road, what are there around roads in a city ?
Lots of buildings = lots of wifi transmitters and cellphone towers.

If this is a movie set where all involved and under the drone flight path will know the risk...its a totally different story.
I used to fly around my home area, only 50 meters here and there not above my house airspace using P1 .
Buildings are all over my place and I do not have FPV back then. I stop at P2. But the last 1.5 years as I am again into flying and I joined multi-rotor forums, I began to accumulate understanding of regulations in various countries, and read many near accidents, seen and read many equipment failures and understanding 2.4 GHZ is way over crowded, and other potential radio interference.... I begin to see potential harm to people and I only now fly in remote areas where the only people is me and my friends.
Interference on our wifi for smartphone or cell service data, at the most caused us delay or broken link or cut off calls. Delay of controlling a multi-rotor due to data link broken, even a mere 5 seconds can mean an accident.
I know its a pain in the azz and super limited playground, but we have to respect other people safety and understand how super popular whore a 2.4 GHZ
is.
If we put our pleasure ahead of people's safety, the drone rules will change big time in negative ways for us.
Loosing money/hardware is OK, but if my drone props blinded a person..how would I forgive myself ?
Lets reverse the role, someone playing a quad on top of my or your head....I will freak out too....would you ?
Use Android wifi scanner ( sorry iOS guys, such App not allowed by Apple ) on a street as crowded as that Seattle 4th Street. You will be amazed at the traffic of 2.4 Ghz and probably 5.8 Ghz too , if today. I live in a 3rd world country and yet if a CBD area like 4th street, my wifi scanner will show so much wifi transmissions.

The logic is simple, the 4-6 props of our small <3kg UAV may not kill people but will easily blind people.
It is a flying lethal eye-blinder, even with prop guards. Come on 7,000 RPM on such a thin blade is VERY dangerous.
Just because the multi-rotor is easy to fly due to the smart engineers giving us good propulsion control on multiple props, does it mean it is less dangerous ?
I recalled before multi-rotor days in the late 90s, my RC friends who owned tons of flying toys, they will only fly their RC plane and including the freakin difficult heli-s on special air fields or remote areas. They don't take off even near their housing complex, they are discipline bunch. Having no FPV is kinda good those days, you tend to fly much closer radius and hence less risk to others.
I think the advancement of the multi-rotor auto controls as in hoover and its GPS assist gave pilots false superiority or safety. The FPV gave pilot sense of false awareness , as he would forgot he needed LOS for the transmitter..but it maybe too late as pilot was so immersed in his video goggle.
I do agree that 30 days jail is too harsh, a communal work would be more humane to punish the said pilot and increase the fine to say US$5K awarded to the Lady. US$5K is cheap for US type law-suit
If the lady goes for something like this,

then it will be national news sensation.
