 SPOILER: McCauleys 30 second rule in action: When McCauley comes  out of the hotel to drive off with Eady, it takes 42 seconds from  the time he first sees Lt. Hanna to when he turns and runs. It takes  McCauley 12 seconds to assess the situation (sees Lt. Hanna to when  he starts to back away from Eady) and then 30 seconds to actually  leave Eady behind.
