There is no such thing as information that is public "in the moment". Once data has been published, it can't be unpublished. Someone will have a copy, and will likely publish it on. This is particularly true wrt crime, there are plenty of armchair vigilantes who think that an arrest is proof of guilt and see nothing wrong with publishing arrest records of people they believe have "gotten away with it". With this in mind, once a record of an arrest has been published, an official published record must persist, so that it can be linked with the outcome. Otherwise those who republish indiscriminately (or worse, those whose intent is to defame) will be able to define the "truth" as they see fit.
