Davis did not experience the same degree of physiological responses as Soden during the shooting. But that's not to say that the night's events didn't leave an impact on him.
For months afterward, he had difficulty sleeping. Night after night, his mind concerned itself with the implications of the outstanding suspect. Would he come back for vengeance?
Intellectually, Davis knew it wasn't likely. But his emotional concern for his loved ones would find him getting up four or five times a night to investigate any sound.
A psychiatrist prescribed some sleeping pills, which Davis refrained from taking. He didn't want to become dependent on some artificial stimulus for sleep. And in time, his sleep patterns improved on their own. Still, it was not an easy period, and there were times he was worried that it would be his wife beating him to death for the nocturnal forays that disturbed her sleep, too.
Already good friends, the three men have grown even tighter since the incident. In a way, they even believe that the lack of available manpower on scene was a blessing in disguise as it minimized the prospect for crossfire and friendly fire casualties.
