I think it's likely to be a variety of people. One of the things the Correctional Investigator has pointed out is that offenders who are better able to write, more literate, better educated, tend to file more grievances on behalf of some of the other inmates who have difficulty doing it for themselves. So there's a cadre of multiple grievers who are doing it because there are problems and they're capable of doing it and taking it on for other inmates. That's certain. The fact that they produce a number of them doesn't mean that they're illegitimate by any stretch of the imagination.
It's hard to determine why certain people are grieving more than others. It could also be that some have certain needs. I've been dealing with one gentleman who has multiple health needs. The correction system has difficulty catering to individual variances in needs. He's not getting his medication on time. It doesn't matter how many times he grieves and says he needs his medication at such-and-such an hour and he's not getting it--the system can't accommodate it. So he needs to keep grieving, because it's the only way that some attention will actually be attracted to that particular problem.
It's a chronic problem that the system has difficulty fixing.
