I would be OK with Flock-like systems if and only if every search required a narrow warrant signed by a judge. The system should show a blank screen without a valid warrant. Until we have that, the tech should be avoided and IMO destroyed. It's interesting the word warrant never appears in the article.
(The very idea that the existence of cameras means cops will truly take vehicle theft seriously is laughable. Perhaps it has improved the numbers in the short term, but laziness will take hold soon enough.)
