Recent violent assaults on University employees and students this week inspired numerous calls for tighter security measures at Harvard and a series of stop-gap measures aimed at protecting students who must walk the streets of Cambridge after dark.

The Committee on Violent Crime--established by President Bok after the late-afternoon murder of Ethel Higonnet--a Radcliffe Institute fellow--held its second meeting on Thursday. Stephen S.J. Hall, vice president for administration and the committee's chairman, said the committee will act to improve lighting in dormitory stairwells and locks on entry-way doors.

Hall also said that the Harvard Planning Office and the Harvard police have been directed to recommend specific precautions to be taken to reduce the risk of violent crime.

Student groups at many of the Houses have suggested ways of reducing the danger of violent assault. Women's groups in Adams and Lowell have demanded intensified bursar's card identification procedures like the one in operation at Currier House, installation of well-lighted University phones, and escort services.

The Quincy House Committee has already instituted a nighttime escort service. Students in the House have been asked to sign up to accompany other House members who must walk to evening classes.

The Lowell House Women's Group said Tuesday that it is considering a whistle campaign. People walking alone in the Square would be equipped with whistles to blow when they are in need of help. Whether whistling in the dark will help prevent crime remains unknown.
