It really looks like something useful, until it will be misused. It is not a matter of if, but of when. So, better to not have this at all, even if the price to pay is if some cases will go unsolved.

You must think about the worse case and consider the consequences. Think about a reelect Trump feeling empowered using such a thing, don't know, to target minorities with his white supremacist ideals. If this is too much for you, consider China with Uighurs instead.

Make this 100x worse considering this is a private enterprise.
