I am writing a thriller, where the MC, who is a cop, is trying to put a gang of crooks in jail, and I have written several outlines, where he and other police use sting operations to lure the villains into traps and trick them into incriminating themselves. But I was told before by others that the felt that the villains were too smart to fall for the sting operations that I came up with, and they would see them as traps. I was wondering, what if the MC took it to much more of an extreme, and kidnapped the gang leader's loved ones, such as siblings or parents... He then held them ransom and told the gang leader, that he has 36 hours to turn himself into the police with enough evidence, to get him and his gang members charged on all counts, for their crimes. Whatever evidence he turns in, it has to be enough for a prosecutor to press charges on all the counts listed in the ransom demand. If he doesn't do it in 36 hours or some other time limit, his family dies. It's an extreme measure on the MC's part, but since the villain is so smart and cannot be caught by other means, the MC figures that extreme measures are called for in this case. However, there is always the risk that the villain would go to the police and report the ransom. He could act totally innocent and pretend that he does not have evidence to support such crimes, that the kidnapper is demanding. There is always that risk of the villain doing that, but since this is the end of the story, I want the MC's plan to work, with no more rebuttals from the villain. The villain has to be accept defeat at this point. If the villain is afraid that the family will be killed from the prosecutor not laying charges in a certain amount of time though, and he turns himself in with the evidence, the family will have to be released, once the charges are filed. So the family will probably then go to the police, and once the gang leader hears that his family is safe, he will then tell the police that he only turned in evidence and gave himself up cause someone kidnapped his family, and he most likely knows who, since he has had problems with that cop in the past. However, the prosecutor or judge in the case, can look at this two ways. Either they will buy the family and him saying he was turned in to save his family, and feel that the evidence is tainted as a result of his claim. Or he will still try the case, and just think of the villain and his family as trying to come up with the story as an excuse to renege on him turning himself in. The judge might just say it's a renege, and their is no substantial proof of a kidnapping, and he cannot drop the charges, just by taking someone's word over it who is most likely trying to renege and cover his arse. What do you think? Is this ending more plausible, for the villain to be brought down and defeated rather than falling for stings?
