The practice of wiretapping has taken a new shape as technology has evolved. Telephone lines are no longer the only communication medium vulnerable to infiltration. E-mail, text messaging, and almost any form of online correspondence is susceptible to monitoring by a third party.

There have been a number of landmark court cases that have shifted the way government respects or rather, doesn't respect a citizen's privacy. Protected under the 4th amendment, which prohibits unreasonable searches and seizures, the right to privacy is not as ironclad as some may think.

Evidence obtained without a warrant was first challenged in the Supreme Court case *Olmstead v. United States.* The Court ruled that the 4th amendment didn't apply to legally overheard telephone conversations. Future cases like *Katz v. United States* and *Smith v. Maryland* push the boundaries of privacy protections.

Luckily the 4th amendment has provided a significant stopping point for government overreach, but it continues to be tested even today, with legislation like the Patriot Act and the Protect America Act of 2007.
