Springfield Public Schools in Springfield, Massachusetts, is the third-largest school district in the state, with over 23,500 students and over 4,200 full-time employees. The school budget accounts for more than two-thirds of the city's total budget, which is approximately $700 million. Yet, they fail to ensure student safety and do nothing to address this problem. As a result, their negligence has led to a major breach of student and employee data. Extensive student databases are now available, containing last name, first name, student number, enrollment status, grade level, home address, home phone number, and ethnicity. You also have access to more than 10,000 company contacts, incident databases, phone records, and medical information. This raises the question: where are the allocated funds going? Why aren't they keeping their students safe?
