Okay kiddo, so sometimes when people are very upset or angry about something, they might start acting out in ways that are not safe or kind. That's what happened in Pittsburgh recently - people were really mad and started doing things like breaking windows, setting things on fire, and hurting other people. This is called a riot.
But here's the thing, it's never okay to hurt people or destroy things, even if you're mad about something. That's why the police had to intervene and try to stop these riots from happening.
It's important to remember that even if we don't agree with something or are really angry about it, we have to find peaceful ways to express ourselves and work together to create change. Violence and destruction only make things worse.
