Misunderstood compliance procedures hardened into accumulated institutional beliefs that blocked sharing.

Evidence

Tragically, these procedures were “almost immediately misunderstood and misapplied” (National Commission of Terrorist Attacks, 2004, p. 79). These mis understandings and misapplications, in turn, led to the evolution of a series of “accumulated institutional beliefs and practices” (p. 79) that undermined or subverted the intended and desired sharing of information. These procedures were widely recognized and even came to be referred to informally within the intelligence community as “The Wall” (p. 79). — Roderick M. Kramer, Geoffrey J. Leonardelli, Robert W.
