Abstract
Prior to March 1, 1971, the Congress of the United States had turned aside all suggestions that any form of electronic security was appropriate or necessary in order to protect it, and the millions who visited annually, against an act of violence. Even though some members of the House of Representatives were seriously injured in 1954 when a group of Puerto Ricans stood up in the gallery and shot down into the crowded chamber, it did not believe that electronic devices or bullet proof glass would be in keeping with its tradition. However, since March of 1971, thinking has changed and modern state-of-the-art equipment and devices are now used daily. A closed circuit television system of over 100 cameras, an intrusion detection system controlled by computer, and low dose X-ray package inspection systems are used at some of the entrances to the buildings.
