Internet and it's downfall

The internet is a big part of society and life today and using search engines such as Google and Yahoo people can find out anything about anything.
This is a good thing and a bad thing because students and adults can keep in touch with family and friends miles away as well as do work online going international with a buisness. There are problems with having internet because of topics such as Cyberbullying and identity theft. Also there is an unlimited amount of information about weapons and materials in the military posted on the web. It seems to be harmless but other enemy countries could just access the internet as easily as any other and look up the blueprints and information on weapons systems and figure out the weaknesses. Even though top secret information isn't leaked onto the internet, weapons that are used today are shown and described.
It is mans right to know what's going on and it's nice to quench curiosity but it could be a malefactor.
