If the US lasts another 50 years I would be suprised. Incidents like this will keep happening, we will all keep arguing about what someone else did and why it was so horrible. Meanwhile what’s going to happen is ithis scenario will keep being played out 100-1000 different ways.
Things like this have been occurring for a long time, it's just that social media and the 24 hour news cycle amp it up. This is a blip in the radar that will be forgotten in a week.
The bigger problem are the folks that abuse said media and want to dox or threaten people etc.
