YMMV / Law & Order S17E9 "Deadlock"

• Complete Monster: Leon Vorgitch is a psychopath defined by his callous regard for human life and his love for murder. Arrested for the brutal murders of five people, Vorgitch escapes from prison, killing two guards in the process. Pursued by the detectives, Vorgitch goes on a rampage, resulting in the deaths of several students he had taken hostage. When arrested again, Vorgitch brags to Connie and Jack that he will break out of prison again and come for them.
• Harsher in Hindsight: Leon Vorgitch killing a classroom of children can become this in the wake of the Sandy Hook shooting (another school shooting incident involving an outside shooter entering the school, rather than being carried out by a student like most school shootings are).
