Yes. We cannot get detailed reports from the RCMP on how they manage to convert a firearm. In the early days we could. We could apply under access to information and get a full forensics report detailing what they did. That is now blocked. We can no longer get a detailed report. They will tell us that they were able to convert it to fully automatic fire, and therefore, it is a prohibited firearm. They don't tell us how long it took, how much machining, or anything else.
