The issue at hand is about those who should be presumed to be innocent. The many who are in a crowd, the majority that are probably not at all related to whatever search is happening.
I've read science fiction where the opposite extreme happens. Where there's an AI that implicitly interfaces with everyone at all times, but it isn't a surveillance nor advertising state. If anyone does actually do a crime there's an actual sentient witness, no need to track down video, and that witness is also able to get help on the way right away. Further there's no backlog of unprocessed data, no file of all of the various normal day to day things that really aren't important.
I could go for a future with benevolent partner AI(s) and no actual surveillance state even though there are cameras and microphones everywhere. I can also see some public spaces (schools, courtrooms, other places people are required to mingle) having observation and storage for a limited (days/weeks) time for manual review in the case of reported incidents.
However the power as it currently stands is much more likely to be used for leveraged persecution and partial enforcement against specific people, and classes of people (IE not rich), rather than for all the people.
