Hi Joshua,
The Crimes_public layer view is, as you note, intended to share with the public. If your agency is not comfortable with sharing the full complement of fields provided out of the box, the layer view can be reconfigured to the fields your agency wishes to share.
With respect to the public sharing of crime data, there are a wide variety of municipal, state, and federal guidelines, including CJIS, which shape what your agency is allowed to share. When determining what to share, often a good place to start is to look at what is redacted when a resident requests a copy of a crime report. A second place to consider is the type of data about criminal incidents that is shared via your crime reporting process to your state and to the FBI. The new National Incident-Based Reporting System (NIBRS) uses record level reporting, is publicly available, and includes 58 different fields. This should give you a sense of the type of data that you could choose to share to the public without running afowl of compliance issues. If you have additional questions, feel free to reach out!
