There was so much wrong with this episode. I will just point out a few things. They never called any type of technical support ie Bomb Squad or Hazmat response teams, especially when they breached the warehouse the suspected builder was receiving his supplies in. Once they breached the basement, Why was an officer trying to punch thru the window with an ax when a drill or saw would have made short work of it and allowed the water to drain while they were trying to cut thru the top. Why is every female a mary sue? John Nolan never checks the gun he is given to make sure it is loaded. Why was he bringing out his suspect before any other police arrived? If this was a super hero or high action show then suspension of belief would be appropriate but not for a formulaic cop drama.
