The devastating irony that all of the therapeutic measures to help children cope with the world they now live in are being taken away hits home. Well done.

This is what it's like. This is what it's like to be in a school and know there's a shooter on campus. This is what it's like to try to hide, to try to protect the students, to try to make the right decisions. This is what the physics of bullets and chemical propulsion do to the body. This is what it's like.

The interaction of the immediacy of being right inside a school shooting and the indifferent facts of what happens when a semi-automatic gun creates havoc inside soft human flesh is only one of the things that makes this play so powerful. There are also the words to the children, "It's okay. Shh;" the emotionless words of the shooter in response to the small child who doesn't want to be there, "Well, you're here"; and the end, which is the beginning, "Shelter in place."
