Minority Report Becomes Reality? 

Remember the movie “Minority report” where future police could spot a crime before it even happens? It may soon become a reality. A Russian company NTechLab claims they have created emotion reading technology that can identify people in a crowd and tell if they are angry, stressed or nervous. Such tool can then be used by police to pre-emptively identify and stop criminals and potential terrorists.
