Google Glass is not just a glass like a sunglass or glasses for myopia. Google Glass is not reliable because you cant now if your computer has been hacked. So your glass can show you -as in augumented reality- thing that is not real. People who use google glass can not be considered as a witness in court. I dont know us or other countries are ready for these. Maybe Its an extreme situation for now :) in future its possible.
