Do people have a need to shoot down airplanes? How about nerve gas? I don&#x27;t see the comparison.<p>The difference is that regular people <i>do</i> have a need for secure communication channels. Even things other than what you typically think of as &quot;communicating&quot; like bill payments and shopping. Encryption is a defensive tool. It keeps people from stealing all your money.<p>Trying to ban strong encryption because terrorists use it is not like trying to ban nerve gases because terrorists use them. It&#x27;s more like trying to ban pickup trucks because terrorists use them.
