I can echo the former NU police officer. The NU Police is a pretty professional outfit, and they take this kind of episode very seriously. Also be sure to encourage your daughter to talk with the professionals in the university's counseling center if she needs to do so. But on the most part, I would say that th NU police do a pretty good job. NU at least has a sign in policy and decent security.
Some schools do'nt even have a proctor.
A friend of mine that goes to a school in New Hampshire once found a guy in his dorm room. So lock your doors and don't sign in anyone that you don't know. However, any time an even occurs such as this security measures that are in place are evaluated and questions will be asked. Any incidents such as these will be posted on the Crime Log that you can read online at home. If you have specific questions regarding the case please feel free to call us.
