In my story, the villain goes free for lack of evidence, and the main character cop, becomes obsessed with the case, and nailing the villain, as well as the other villains, who he does not know. So eventually he steals the keycard of the lawyer who defended the client and got him off. He uses the keycard to break into the law firm building and look in the lawyer's files on the case. He reads about what the client told the lawyer, of what really happened, in the lawyers reference notes, and finds out that there is a corrupt cop working with the villains, that was assisting them in the case. A mole pretty much. Now the MC cannot use this as evidence at all, since he broke in to have a look at it illegally. He is just obsessed with finding the truth, and couldn't have found a potentially better place to look so far. He just wants to know the truth, so he can then formulate some sort of plan to get evidence that he could make admissible later hopefully. So he is just using the lawyer's case file and notes, as a guide only. But I was told by a couple of lawyers that I asked on how this would all work, that it's a plot hole, cause logically a lawyer would not make any reference notes, of one of the cop's in the case, being a mole working for the gang. However, this was a protected conversation between the attorney and the client, so if it's protected, why would a lawyer be worried about writing it down? I thought that protected conversation meant protected, period. And that if someone else read that a cop was corrupt in there, the information was legally immune from being used, since it was a protected conversation. But I was told that this is not legally correct and therefore plot wise, a lawyer would have no reason to keep this conversation written down, especially of there was a secret mole cop in it. So if this doesn't work plot wise, I was wondering how can the MC find out who the corrupt cop is? The only ones who know it is are the corrupt cop (which the MC doesn't really suspect at all, or has no evidence to suspect), and the defendant, and the defendant's lawyer, should the defendant decide to tell the lawyer, so the lawyer might be able to use that information to build a possible better defense. So, how can the MC find out who the corrupt cop is, when only two people besides the corrupt know, and the MC does not want to coerce them into talking or anything cause that means too much trouble?
