Devil is in the details, but hey let's not pay attention to that. She isn't charged with "rigging a homecoming".
You're right.
She's accused of rigging a homecoming by using all of the illegal activities you listed, but did not ever injure or kill anyone.
Yet she is being prosecuted to the fullest extent of the law while people who actually DID injure or kill people are given plea deals or had their charges dropped.
Good job missing the obvious.
