No, not really. People have been jumping from heights since at least biblical times. Also not an excuse to prevent putting in at least small ventilation windows.

In Europe, schools were opening their windows to let in fresh air during the covid pandemic to cut down on disease transmission.

Meanwhile in the US, we hire architects that design our schools like prisons, and end up with sick building syndrome because there are no windows that open.

Did you know the children who survived the mass shooting in Uvalde Texas were able to escape because they were in an older school building with windows that open? Good thing we don’t build our schools (or any other public buildings) like that anymore. 🙄
