We learn in this episode that Phil's middle name is Freemason.
Phil's fiancee Cindy makes an appearance in this episode for the first and last time.
When Howard is demonstrating the miniature tank in front of the chief and the commissioner, the tank changes positions three times in the model of Sniper Alley, in between shots when Howard demonstrates the flame thrower.
In the beginning of the episode Furillo is standing in his office talking to Henry and holding a cat. He's holding the cat so that it's draped over his forearm, away from his body facing Henry, but in the split second that it pans from Furillo to Henry and then back to Furillo, the cat is in a different position, nestled against Furillo's chest.
In this episode Furillo doesn't seem to understand what a gang member means when the man asks what 'the sugar' is (a reward for doing something, usually sex or drugs). In the pilot, however, Furillo had no problem understanding the very same idiom when Jesus Martinez used it.
