(2) Security should apply, generally speaking, to units as a whole, taking working units up to the limit of face-to-face working acquaintance as a base. It is unsound procedure to give certain individuals a higher level of information than others, since the privileged individuals will be tempted to display their inside knowledge, and the underprivileged individuals will be goaded by unwholesome, resentful, and acute curiosity. Either the entire unit should be given the information, or denied it. (3) Security should not be applied for editorial purposes. Censorship is a separate function. Improper security procedures, vesting arbitrary powers in stated officers, may tempt the security officer to express his personal literary, artistic, or political preferences under the guise of maintaining security. The inevitable consequence is the breakdown of both security and of procedure. Censorship should be applied in conformity with national or theater censorship policies. Review and estimate of radio or leaflet output is another function. (4) Security for printed materials is easy enough to maintain. The leaflets can be sent to the G-2 to check, or wherever else security functions may be vested. Radio security is another problem. Experience in World War II indicates that spot news cannot wait for routine security, but must be processed through. Two types of control, supplementing one another, are desirable: _Security liaison_ on a 24-hour basis should be available to the radio operatives for the rapid processing of military news. The security duty officer should be indoctrinated with an attitude of cooperativeness, based on an understanding of the value of propaganda, and should conceive it as his mission to explain the needs of radio propaganda to his superiors, rather than taking the attitude of being superior to the radio operatives. There is a sound psychological reason for this. The presence of a sympathetic security officer will increase cooperativeness on the part of the propaganda broadcaster. An unsympathetic one will merely maintain the official dignity of his office and position. High morale on the part of script writers is more important than high morale of security officers.
