Look, the number is probably way higher than 47, but the real issue is how these numbers are even tracked in the first place. Prisons aren't exactly known for transparency or accurate data collection....
Sure but if they're tracking it at all, that implies some level of data collection, even if it's incomplete or flawed. The existence of a number, even a low one, shows the system is trying to categorize something, which is itself a point of contention.
