Why does it seem that access to buildings on the Longwood Campus is more restricted than access to buildings on the Cambridge campus?

Universities and colleges are constantly struggling with the appropriate balance of security and freedom of movement. Appropriate levels of security are determined by schools and departments in coordination with the HUPD. Regardless of how secure an environment is, community members should still take appropriate precautions to protect themselves and their property, such as by securing their personal property, locking their doors when leaving a room or office (even for a moment), and calling the HUPD immediately when they observe suspicious activity.
