- "Few presidents have ever granted the Fifth Freedom. It's the right to defend our laws, by breaking them. To safeguard secrets, by stealing them. To save lives, by taking them. To do whatever it takes to protect our country. The Fifth Freedom is mine alone. I am Sam Fisher. I am a Splinter Cell."
