> cops have been tracked down and killed by people using apps like Waze

Do you have a source for that? I can only find 2 examples vaguely similar but neither are really what that statement claims. Specifically one of them was just cops making stuff up about wayze which was factually incorrect.

> police have access but at least ostensibly have oversight from the legal system

We've already seen plenty of examples of cops tracking ex-wives and such similar abuses with no real accountability - nobody's lost their job over it

Cops know exactly what they do when they show up like this, it's meant to intimidate, there are also plenty of cases where cops have repeatedly crossed the line harassing citizens breaking no laws, it's disgusting
