Fourth Amendment Privacy

The fourth amendment states that unreasonable searches or seizures are prohibited unless they have a warrant. the fourth amendment grew directly out o the colonists experience of unreasonable searches of there privacy and personal property. Even the king did not have the authority to search his peoples homes although government agents were allowed to search homes if the reason was lawful and they had a warrant. My family thinks this amendment is very important because of whats happening right now with the internet and individual surveillance. its more important than ever. The controversy is that the NSA and commercial (i.e. google) surveillance are eroding our privacy. I think the whole thing with the NSA seeing our emails is really creepy.
