This NYT article discusses a 19-year-old kid that has been arrested in Britain for computer hacking crimes. This relates to globalization because the Internet has become an important commodity for much of the world, but it's not a resource that any countries "produce". However, a person in one country can cyber attack a system in another country just as easily as they could in their own country.
Individual countries can set up their own laws as to how their citizens can and cannot use the internet, but these laws might not apply to a hacker in another country. This shows why it could be necessary to have international treaties and laws to help govern and regulate the use of the internet and prosecute and possibly extradite cyber criminals accordingly.
The question of Internet law also brings up questions of how information is controlled, shared and regulated. Who should make the Internet laws and are these entities nations, corporations, governments, or some other kind of regulating body that can has the ability to apply itself globally?
