It's easy, actually.

A guy create a website and sometimes people used the website to do things that can considered not good.

Police came for him while he was only the creator of the website (6 yo understood the difference immediately) and put him in jail.

His mom worked relentlessly to make him free.

Today he is a free man, they can hug each other and justice has been made.

She asked why today, I told her about the new president and she asked why the others didn't help, and many details about prisons.
