There were no kids or staff in the halls when the cops swept through because that was part of the school’s active shooter plan. They were on lockdown inside their classrooms.
According to police statements, right before they shot her, she was firing through the window at police cars outside. Watch the video again if you need to. You can see she had shot out that window and you can see the cop cars out there.
Please, just stop with this “Sandy Hoax” nonsense.
Not in the classroom, too.
