1. It's clear that Emily Proctor is being showcased while Kim Delaney has already started to be moved aside. Delaney's character was barely in this episode. 2. Given recent events, the "sniper on the loose" storyline might be considered to be in poor taste. However, I think that this episode had to have been shot long before the D.C.-area killings. 3. One minor flub in the episode. Caruso's character says Gilley suits are used for camouflage in the desert. They're used for camo in almost any environment.
