Nightmare Fuel / Magnum Force

• A soon-to-be Asshole Victim murders a prostitute by force feeding her a bottle of Drano. The fact that this inspired the real-life murder of three people makes it even worse.
• A drug dealer's mistress gets shot twice during one of the vigilante executions, but isn't killed outright and is still screaming as she falls to her death twenty stories below.
• Harry's confrontation with the remaining vigilante cops has some chilling Ax-Crazy dialogue and ominous cinematography.
  Harry: You "heroes" killed a dozen people this week. What are you going to do next week?
  Davis: (flatly) Kill a dozen more.
