After the police cars and truck stop next to the yard with some containers, several SWAT officers step out onto the sidewalk towards the front of the truck. After the cut to the first car from which Sal emerges, the sidewalk is empty and the officers come out from behind the truck again.
There are several radio call errors. Conversations with neighborhood sector cars usually use the precinct number followed by a alphabetical name, so Eddie's car might be "6-5 Adam" or "6-5 Boy". The response to the dispatcher would be to "Central", not "Central 1". Also, the reference to a "10-10 in progress" is incorrect. A 10-10 in the NYPD radio code is to a possible crime and should carry with it the nature of the crime. And it can't be in progress if it may not be a crime at all.
When Eddie comes out of the room with the inquiry board he stops and talks with this trainee before the trainee was pushed into the room. As his trainee is pushed in you can clearly see that he still has his pistol holstered. Police are relived of their weapon pending an investigation after any on duty shooting, the inquiry board is one step in an investigation so he should not have his gun at that point.
