Obviously an unpopular opinion on this site, but I wish we had speed cameras, red-light cameras, and ALPRs everywhere. Cars are incredibly dangerous and large numbers of people drive them like absolute lunatics. There should be absolutely no expectation of privacy when using public streets. That position doesn't even account for the footage helping immensely with other investigations.
You managed to say everything but the difficult bit. People don't generally have a problem with cameras, all our computers and phones have one. The problem is who can use them and when.
I would totally agree with you if I trusted the government
> There should be absolutely no expectation of privacy when using public streets.
Strong disagree. Life in public areas is often still part of private life. And we should treat it with the respect and privacy that it deserves. You going to the doctor? That's part of your private life. You meeting with an old friend to catch up? Also private, even though you do it in a public cafe.
