The arrival of multiple officers, flashing lights, gathered crowds and people filming on their phones can make even a relatively contained incident appear dramatic.
And once photographs of that scene reach the internet, the cycle can become almost impossible to stop.
One person sees an image and asks a question.
Someone else challenges that explanation.
Then another post appears claiming to have additional information.
Before long, people who were nowhere near the scene are discussing the event as though they had witnessed it themselves.
That is why authorities routinely encourage people to wait for confirmed information before accepting claims circulating online.
In the immediate aftermath of an unexpected public disturbance, details can change quickly.
Witnesses may have seen only part of what happened.
And photographs can be interpreted in several different ways.
What looks frightening in one image may have a completely different explanation once the full circumstances are known.
Still, there is something undeniably fascinating about moments like this.
