Methodologically, we control for sentence length, so you have an equivalent group. What would distinguish the two? Well, one would be where they started off first. Most of them started off initially at higher security levels, medium security, relative to the other group. That can be part and parcel because of the nature of the offences they were convicted of, such as drug offences plus attempted murder plus organized crime offences. They are very serious offences, and the severity of that drives upward your security level placement, combined also with the issue that there are some provisions for eligibilities later, if you're convicted for a criminal organization offence. In general, then, they would stay longer to begin with.
