When you walk around Mudd late at night, you can see why people feel safe here. There's always music playing. People are always outside studying on couches. And a security officer (or two) is always patrolling the parking lots. Nobody at Mudd locks dorm room doors. It's just assumed that students will take care of each other's stuff. People know that if they lose something and it's found by a Mudder, it will get returned. The Honor Code system is one of the most powerful security devices on this campus. People live by the Honor Code here, so the only thing to be remotely worried about are occasional random incidents that happen off campus. All of the academic buildings are always open to students, too, so there is a very trusting environment at Mudd.
Harvey Mudd's security thrives on its feeling of community, as opposed to an invasive task force of security. It's not that there aren't any officers; it's just that the Honor Code removes the need for trivial security concerns found on other campuses. Mudders are entirely comfortable with each other and promote a great sentiment of trust. In contrast to larger universities, at Mudd, students don't worry about their fellow students making off with their possessions. There are occasional off-campus incidents, like people trying to steal bikes or skateboards. Cars do get broken into, but mostly during break when no students are here. Aside from the occasional random incident, though, Mudders tend to feel safe at HMC.
