I think that they are pushing the limits. A lot of small cities, like mine, are on the fence about drones. My local city council gave a neutral response to them, "Do it safely and in areas that pose no risk to the public, follow state and federal laws."
But if people are starting to do dangerous things, that neutrality or even timid support goes away. And its not the bridge dive that is the issue in my opinion, its what does it lead to. This week its bridge dives, next, through busy parking garages. A line has to be drawn before someone gets the bright idea to race one through a busy super market.
I love flying my drone, and talking to kids, parents and anybody vaguely interested, but if they see "Drone mauls innocent bystander" in the news or on social media, that interest turns into disdain or worse.
