“Balance” arguments are always fallacious and only lead to increasing surveillance. The real conversation should be about limiting surveillance to only what is absolutely necessary and proportional.

“Balance” gets you to “Well, we would put the cameras in every room of your house, streaming back to law enforcement, but we’re willing to find a balance between privacy and security so we won’t put them in your bathrooms”. Whereas of course, assessing whether it’s necessary or proportional, putting streaming surveillance cameras in people’s houses would fail both tests.
