Like I said: there are legal exceptions to what becomes public. Do any apply? I don't know, and that is frequently litigated. Like you point out, there are frequently countervailing public interests at stake, but as the old saw goes: bad facts make bad law. You don't want to start poking holes in open government laws based on a high profile example of the law maybe not being perfect.
It does happen from time to time where a highly sympathetic individual asks for public information to be withheld because it's about them, or a loved one, and its highly sensitive even if it's not legally protected. The correct approach, IMO, is to accept that these instances are the exceptions, not the rule, and are the unfortunate cost of having a robust public access/oversight law.
"The needs of the many outweigh the needs of the few", all that stuff. Because once you start giving government (and law enforcement in particular) the discretion to say "Nah, we think this is inappropriate/not important enough to release" it threatens to make the rest of the law moot.
But as applied here and without getting into a slippery slope argument full of hypotheticals, I'm not weeping tears of sadness for a grown-ass man who made the decision to knowingly engage in illegal activity and now is faced with real life consequences of that action. This is not the hill to die on.
