I have an idea for a story, but want to know exactly what would happen first. I tried doing legal research but have gotten some mixed opinions so far. But I would like story lovers' opinions, as well as legal ones. In the idea, these characters want to acquire certain materials from a gang leader, and kidnap the gang leader's loved ones, to hold them for ransom so the leader will deliver the goods. But the leader wants help on getting his loved ones back and knows that the police will do a better job at rescuing them at the ransom drop off, rather than his own gang. The police just have better resources and training for that sort of thing. Even though the kidnapper says 'no police', he does what a lot of characters do in fiction and rely on the police anyway. However, the ransom he needs to turn over, will implicate him and his gang in past crimes. It's basically most likely a video disc with some stuff on that will incriminate them. There could be other contents other than the disc that will, but I haven't gotten far enough in the story yet to tell what they would be. But if the gang leader goes to the police and explain the kidnapping situation, he is going to say that they want him to handle over a 'package' that he has in order to get them back and want's the police's help. The police are going to ask him what the package is, that they want, and he will have to do something like tell the police he is pleading the fifth, and not going to tell them what it is, or what is on the disc. Now as I understood the law in my research, the police cannot look at the package, just because he pleads the fifth. They cannot get a warrant do so, cause he, as a private citizen has a right to privacy. Even though he is a criminal, he has not been caught, and has no record. The police know about the gang, but they have never even heard of him till now, when he calls them for help. And he never mentions he is a gang leader of course. So as I understood it, the police cannot get warrant to search the package, just because he exercises a right of his. Even if the ransom drop off, goes well, the police rescue his loved ones, and get his package back from the kidnappers, the police will still legally have to give the package back to him, not knowing what it contains. So with this in mind, would the police still have some sort of response to this, realistically, if he refuses to give up the info and remain silent on what it is? Also when receiving instructions from the kidnappers, the kidnappers may divulge information that will incriminate him and/or the package as well. So would he be able to tell the police "even though you are helping me get my loved ones back, I still am going to listen to all the ransom instructions in private, under my privacy rights"? Would the police still have some sort of legal response to this, that will cause the gang leader trouble, or would they just have their hands tied and be forced to go along with it?
