Emerging technologies can have a dramatic effect on many aspects of society, from how business gets done to how people interact with each other.

But what about one of the most important issues of current times, namely homeland security?

Do emerging technologies like blogs, wikis and video phones impact the way that people and governments report on and respond to terrorist attacks and natural disasters?
