If you see someone you do not know, ask the person to identify himself or herself. Thefts have occurred in studios and labs when students have been afraid to challenge strangers. If something strikes you as suspicious, report the incident to the guard immediately. Don't leave anything valuable in your locker overnight. If you bring a bicycle to school, don't plan to store it here overnight or during vacations.
Unattended objects tend to disappear.
At Home Don't advertise. If you put a note on your door saying you aren't home, you're asking for trouble. Use your last name and initial only on door, mailbox, and in your phone book listing. Install a peephole so you can see who is outside before you open the door. Do not open the door unless you know the person.
