I believe that the indicator of the 5,000 hits a day is more of what we call an activity indicator than an indicator of effectiveness. So those law enforcement people who use the registry would have to give an assessment as to whether or not it was useful to them.
There could be 5,000 hits, and they could say yes, it was very helpful and helped me in this way; or they could say no, it wasn't helpful because the information wasn't correct. It takes an additional degree of interpretation or information to assess effectiveness.
