The thing that struck me was the fact that [the shooter] knew where [Thompson] was going to be and when he was going to be there. Generally, you get that information by observing the individual. You find their schedule and their routine, and then you intercept them somewhere along the line on their routine. This was obviously not a routine setting. So he had to have some reason to believe that Thompson was going to be coming out of that door at an approximate time to be able to lay in wait. Because it’s Manhattan, standing around waiting risks the likelihood of being challenged by a cop or security guard coming by, which suggests that he had reason to know when the guy was going to be coming out. It suggests some sort of inside information.
