Again, some things, such as aquittals or mere suspicions, could be buried in paper files never to see light again. With computerized indexes, that is less likely.
"Privacy" is a relative term. Thanks to the Internet, something "public" gets spread around worldwide instead of restricted to say one's own neighborhood. You say "could've readily been found if someone wanted to go to the print archives". But that is a huge IF. Most people do not have the time or resources to search through print archives. Often the archives are not indexed, so one needs a date in advance to narrow the search. Often the archives are serial microfilm, so that means physically travelling to an archive, loading a roll and checking each and every page for a reference. That takes time, lots of it. Having done it, I can say it's not easy. In contrast, electronics allow comprehensive searches from one's own desk.
I submit that the Internet and computerized indexes and archives makes a HUGE difference in "privacy" compared to the past of paper files or microfilm.
All true. The worst part is that these restrictions REDUCE our safety, not improve it. Many ex-offenders, unable to literally live with the new restrictions, simply go underground. They are no longer tracked by parole officers or counselors which increases their risk. Further, many get bitter and frustrated at not being able to earn a living and return to crime. But this is a very hot button issue in society; anyone who raises it is accused of coddling criminals.
