Giving the public full access to something like that would be asking for trouble. We've already had one serial killer, if someone else decided to go on a killing spree I'm sure they'd love to have a map of everyone's whereabouts. A short list of authorized persons should be enough, a reporting system could be setup to notify administrators of a missing person so they could relay the information back. Requests would be logged, and to prevent abuse we may need to limit who is able to request location data on a "missing" person. Each person with a tracking device could provide a list of trusted or un-trusted persons to limit who might be able to ask for their location.
Security breaches could also pose a serious issue due to the nature of the collected data, so an emergency lockout system would be necessary before going live. Something that would be able to remotely deactivate all tracking devices if someone with ill intent gained access to the system.
Hmm. On second thought, this may take a bit longer than my original estimate. [if it fell into the wrong hands, that could be disastrous... and he'd need to decide who he can trust to handle administrative roles, and teach them how to work with the system, so he'd also need to make sure everything is accessible and understandable to people besides himself... ugh, it's way too much work.]
