A lot of my ability to do threat assessment (like pick potential hostiles out of crowds or tell which stupid boat is full of raiders instead of curious locals) is based on pattern matching off a database of human behaviors. The Targets were anomalous, but they weren’t so anomalous they didn’t exhibit the same basic types of behaviors as other humans. And something was off about their behavior in the control area foyer, something that couldn’t be accounted for by their overconfidence or the fact that they were all assholes.
