Yes. We can look at the personal identifiers we collect. It's an encrypted version of the accused's name, the date of birth, sex. Within a specific geography we can look back at the criminal history information that we have with that key to identify whether or not there were prior convictions.
For this slide in particular, slide 11, we looked at those 10 offences that had the provisions for the four-year mandatory minimum sentence and we looked back within that history to see whether or not there were prior convictions of that same type. We found that seven in 10 did not have a prior conviction of that type for that year. So in 2003-04, the 133 people who we were able to identify clearly did not have a prior conviction of that type. They may have had another conviction of a different type.
