FYI:
I believe that the justice department's major cross-sectional survey of crime rates, but the Bureau of Justice Statistics' flagship survey, the National Crime Victimization Survey (NCVS), is done through statistical sampling rather than through police reports. Rates of reporting (or conviction) thus aren't really germane to the question.
Only one of their major surveys, the Emergency Room Statistics on Intentional Violence, seems to work on a reporting rather than survey basis, and even then they pick a representative sample of hospital emergency rooms and monitor those.
