In 21th century, technology breakthrough rapidly. New weapons, electronic devices, culture, and systems were invented and change a lot. When internet was invented, it wasn't that popular. Internet was for US military to send a message each other from west to east. Few years later, Microsoft came out and different companies came out; internet began to develop more. Internet is really significant object and many smart systems invented. Users are sincerely using for searching, email, contact, study, etc. It became technological, internet and electronic devices.
Development of internet and computer making the world better place, in other hand, internet is using negatively. Internet leads users put into death and depression. Also it can uses as killing somebody or threatening the countries. That is why, US government and other countries government are trying to interpret the emails and information to prevent the situation. I think it is the good thing to do however, it can disturb personal privacy. Someone is observing your privacy and secret information, who will love to say "it's okay!" Nobody will say that. US government needs to stop interpreting our emails.
