The Safety Patrol is a service ran by Westmore Middle School. It's purpose, as seen in the movie, is to act as the "police" of the middle school. In the Diary of a Wimpy Kid (film), Greg Heffley refers to it as "the cops of middle school." Various tasks Safety Patrol members have to preform include: walking pre-schoolers to their day care and enforcing the laws of the school. Safety Patrol members have a lot of privileges - free hot cocoa, missing 20 minutes of Pre-algebra (Which, to Rowley, is a bad thing), and protection from bullies. It states in the first book that anyone who picked on a Safety Patrol member would be suspended immediately in consequence.
