I have a story, and I am not quite sure how to end it but have a few options. It's a crime thriller, and one option is for instead of the police coming to bust the villains, they want revenge on them for how they keep on getting away with their crimes. Since it's a screenplay, I tend to use movies as an example, and one movie that ends like that is Lethal Weapon 2. In that movie, the cops cannot arrest the villains because the villains have diplomatic immunity. After the villains get away with their crimes too many times, the two main cops decide to go kill them all. The two cops level the South African consulate to the ground, and kill a couple of dozen South African diplomats, since they were not legally able to touch them. Then at the end of the movie, everything is fine. In Lethal Weapon 3, they are still cops, who got away with mass murder, and nothing happened to them. Lethal Weapon 3 also has a similar ending. They decide to go kill the villains themselves, since the law is not doing anything about it and the way they get to the villains would not hold up in court at all, since they use death threats, and torture against criminals to get answers as to who is behind at all. So with doing that, they would never even be able to argue that they any probable cause to go shoot all of the villains later, since the information that lead to them was obtained through illegal means. However, in the third one, when they confronted the villains, they pointed their guns at them and told them to freeze, which is kind of a plot hole, because if they arrested them, they wouldn't be able to legally bring the case to court, so you might as well shoot without warning. Yet at the end of that movie, everything is fine, and the characters are still cops, and are happy and free. I was wondering, how do you write a story where the reader will enjoy an ending like that and be able to suspend disbelief? How do you get them to believe that? I was trying to research some real life examples of where something like this happened in real life, and the only one I was able to come across was Wyatt Earp, but that was over a century ago, and things have changed now. One idea, for my story off the top of my head, is that the cops who want to bring the villains down but cannot legally, could kidnap the leader of the organization's wife and kids, and threaten to kill them, unless the leader kills all of his subordinates, and then himself. He also has to make the police and the media, find the bodies in by a quick deadline, so they can all be confirmed, dead, or his family dies. The downside to the plan is is that they would have to believe that the villain would actually be willing to do that to save his family, rather than risk calling the honest cops for help. But that's just one idea, of how to get them, I could use others. So is their anything to be mindful of, when trying to make an ending like that, believable? Thanks for the input. I really appreciate it .
