We have different versions of the uniform crime reporting survey. In our earliest version--and I think we were talking about this earlier--that is correct. We used to count incidents according to the most serious violation that occurred within the incident. However, we have a newer version of the uniform crime reporting survey that can capture up to four violations for each incident that occurs. In other words, we have information on the most serious as well as up to three other violations.
