I might add a few comments as well, speaking as a researcher and as an empiricist. Without clear data, we don't know where we are now. If we don't know the scope of the problem, the full range of the problem now, how will we know if we've had a positive effect or if we've had no effect whatsoever?
Really, in order to be able to assess and then demonstrate the effectiveness of whatever it is we do with our strategies, our approaches, our framework, we have to have a good sense of where we are. And that requires better surveillance, better data collection than we have now.
