Diplomatic Immunity is a privilege, not a power granted to diplomats. It does not excuse a diplomat from felonies, but does prevent the diplomats detention or arrest for minor offenses. It also does not protect him from arrest or detention except in instances when he is conducting the official business of the nation which he represents. It is quite necessary, as if diplomats did not have freedom to conduct their business without fear of interference, international relations could be seriously impaired. It should be noted that the Constitution of the United States prohibits the detention of members of Congress which would interfere in the conduct of their business except in cases of felony, treason, or breach of the peace. Diplomatic immunity renders the same protection to official agents of other governments. The sensitive nature of diplomatic relations, the need to communicate freely are all important features to be considered in granting diplomatic immunity.
