It doesn't automatically, but literally everyone claiming the Navy was "hiding something" was going down the conspiracy theory route. I'm not talking about generalities, I'm talking about the specific situation in question which is the Titan sub.
>the information is OK to release publicly from a security standpoint.
What information are you referring to? It's already public that the navy has the system in question. It's already public that it is analyzing data realtime. Nothing about the system would have been compromised by publicly announcing they had detected an anomaly the day of the event vs 4 days later. The logical conclusion is that all of the aforementioned reasons are why they waited 4 days. You don't need clearance to get to the conclusion.
So what we know is it took no more then 4 days to categorize it. We don't know whether or not the system flagged it immediately, or flagged it as part of background process, or how long that took.
Joe Internet-Commentator looks at that and says "oh it was totally instant, probably".
Bill Submarine-Commander for a Hostile Power on the other hand is very interested in exactly how quick any particular detection was, to what resolution, and what implied noise-cutoffs of the network. What sort of sonic events are handled in real time vs. handled in later analysis. Because for Bill the question is "how long before I'm detected and surface ships start dropping buoys, depth charges and torpedos to kill me".
Kind of, yeah. There is a good timeline on when the ship was in water, when an event would have occurred, plus a very narrow geographical search area. That is significantly more information than is ever available when chasing ghost submarines.
It is difficult for me to imagine some bored analyst did not pop open a graph of activity within a 30 minute window of suspected loss of contact time for the area. If detectable, a ship implosion is likely a pretty aberrant signal in the data.
Have you worked on classified detection systems? Actions and conclusions don't always appear to follow logic when your priors are wrong.
