This document summarizes a research article about school shootings as organizational deviance. It discusses how school systems have a bureaucratic structure with centralized control through rules and procedures, but teaching activities are loosely coupled, giving teachers autonomy. This gap between policy and implementation can allow student issues to go unnoticed until becoming destructive, as in school shootings. The document also notes that while schools have access to student information, this data is not always communicated between people playing different roles in the system. It suggests teachers and community members should work together to promote student comfort and identify early signs of depression to prevent violence.
