Even at the moment of death, Haver couldn't understand: how did he die?
In his calculations, the worst-case scenario was Dean remaining unfazed by the threat and returning directly to cause him trouble. But he had already placed informants here at the precinct. If Dean returned, or mobilized patrol officers to this office, he would be notified immediately. Besides, Dean wouldn't know if Haver was still at the precinct or had already left with Daisy. This would take time for Dean to ascertain, and time was precisely what Dean lacked.
Even in the absolute worst-case scenario, where Dean managed to corner him in the office, rescue his colleague Daisy, and point a gun at him, Dean would still want to know the location of the printing plates, wouldn't he?
