Input: Jason Gideon:  When we 're dealing with a bomber , we 're talking about someone who 's non - confrontational . If you bumped into him at a cafe , he 'd apologize ; even if it was n't his fault .
Aaron "Hotch" Hotchner: We would classify this bomber as highly organized , based on the meticulous design of his bombs . It means above average intelligence . He probably has a skilled job , a trade , _ one _ that allows him to work alone . That 's how he was able to make a sophisticated device without raising suspicion . Furniture maker , jeweler , et cetera .
Detective Morrison: Background in explosives ?
Jason Gideon: No , not necessarily . You 're thinking about a type who likes to blow things up . Gives them an emotional or sexual release . Death ? Secondary .
Officer Worthy: Then what 's this guy doing ?
Jason Gideon: Murdering . Bombs ? Just weapons . And these attacks , they are not random .
Officer Worthy: Well , how do you know that ?
Aaron "Hotch" Hotchner: By process of elimination . We know bombers fall into a discreet number of categories according to motive . There 's the terrorist , whose aim is to spread fear ; we expect him to strike in a populous area like a subway . There 's the politically motivated bomber ; he makes a statement by choosing a symbolic target like an abortion clinic . Then there 's our unsub . He made bombs designed to kill and he chose his victims specifically by placing the bombs at their stoops . That tells us he has a direct motive . Statistically , he bombs for profit or to conceal a crime . And it tells us how we 're going to find him - through the people he killed .
Jason Gideon: Somewhere among the three victims there is a direct motive . Keep digging .
