I can 100% guarantee the current hardware iteration will never support always on recording. It would kill the battery in 45-60 minutes. That added to the fact that almost everyone has a phone on them that can already be geolocated makes using Glass unnecessary for tracking. You could argue that Glass would be useful in taking a photo snapshot every minute but with the growth of security cameras it's estimated that in some areas people are caught on camera as many as 300 times/day. That makes Glass not all that useful.
