The FBI is developing thru a consultant what they are describing Identifying Warning Behaviors of the Individual Terrorist . As they are quick to point out its still in a research stage. But the first warning behavior they call: 1.Pathway warning behavior—any behavior that is part of research, planning, preparation, or implementation of an attack (Calhoun&Weston,2003;Fein& Vossekuil,1998a,1998b,1999). Which encompasses most of what CTI teaches in detecting terrorists during their pre event stages. The paper goes on to discuss 7 other warning behaviors. But they are aligned more with delving into an identified suspect. Still the warning behaviors are well worth the read.
