It's a shame cops can't be trusted to not abuse it if given access not through the courts. Every single time a tool like this is given to them without massive fetters it's abused so they don't get to have the toy.

There's a ton of things that would make policing easier but we don't do them because they destroy other valuable parts of society. It'd be much easier to solve crimes if everyone had to wear networked body cameras and GPS trackers at all times but we don't do that because it destroys far more important things.
