We have policy around nuclear attacks that aren't based on actual nuclear attacks. There are policies around preventing certain people from being assassinated even if nobody's assassinated them yet. If “swatting” is something that we know happens in this sort of case, we should review our procedures around preventing it if circumstances change in a way that we could reasonably expect would increase swatting.
In any case, this logic is tantamount to:
"We don't see any immediate threat to posting the first 3 digits of victim's SSN in the transcript, and they don't have any ID theft criminals yet, so let's just post the first 3 digits for the hell of it."
Residential address is equally unnecessary. No need to post their address for the hell of it.
