I suspect the restriction is impossible to enforce, because it's almost certainly the case that the facial recognition isn't performed on the device itself. So it's a bit like saying you can't use the things for pornography; you'd have to know somehow that the user intends to pleasure himself later by looking at pictures of ladies' shoes.
It's a bit too late on that score anway. Having boots on the ground is an anachronism, even if they've got high tech wearables. In 2000 Scotland Yard was able to foil the Millennium Dome diamond heist by tracking all the gang's preparations using a network of public and private security cameras. There was almost no in-person surveillance. The first time the gang was physically near the police was when they were surrounded by an armed response team inside the exhibit hall.
Here in the US, the NYPD has acquired similar, possibly even more advanced capabilities. They can for example find all the six foot-ish blond men wearing blue sweaters in a one block radius of Penn Station then run their images through facial recognition software, then follow their suspect almost anywhere in Manhattan with no chance of being detected.
In comparison to camera networks, having a cop wearing Google glasses isn't that big a deal. A lot of our legal privacy protections are based on the assumption it's too labor intensive to follow people around for frivolous purposes. An army of cops with cameras is expensive to maintain; a network of surveillance cameras is not.
