Great, for added big brother points, the government could literally listen to every conversation on every street corner...

Edit. Perhaps someone could enlighten me as to why the police having live recording microphones everywhere is a good idea, generally you'd need a warrant to record citizens.

But sure, this is just for loud exhausts and has no other possible uses. Lol!

China’s ambition to collect a staggering amount of personal data from everyday citizens is more expansive than previously known, a Times investigation has found. Phone-tracking devices are now everywhere. The police are creating some of the largest DNA databases in the world. And the authorities are building upon facial recognition technology to collect voice prints from the general public.
