Apparently, there may be yet another reason to be underwhelmed by the iPhone 5s: a lawyer named Marcia Hofmann, writing for Wired, offers the opinion that its fingerprint authentication might end up eroding a long-cherished legal right.
In this case it wouldn't be the government chipping away at your statutory protections, but technology itself.
The protection that Hofmann thinks might be at risk relates to self-incrimination.
