I was told by some readers that I have a plot hole in my story, in the sense that the criminal characters behave implausibly. I was wondering why they do though, or I do not understand the plot hole, people have told me. Basically the gang has recruited a new member, but they want to make him a full trusted member, cause the man has connections that the gang could use. He's a cop. A crooked cop, but a cop no less, so it's risky recruiting a cop, but advantageous cause he has connections in his job. So the gang wants to give the new recruit a 'blood in', that is is that they want him to spill the blood of another person as a test to get in. It's a realistic technique that gangs use. However, since the new member is a cop, and could be undercover even, to aim to want to get evidence on the gang and bust them, the gang has to take precautions. The gang does a fake blood in on him instead. They get one of their own members to pose as a potential victim, and the cop has to perform the blood in, with an unloaded prop gun, not knowing that it's staged, to see if he can do it. It's kind of like how in some books and movies, a gang will give someone an empty gun, to see if he will shoot someone to see if he is not an undercover cop, but they do not want to give an undercover cop a loaded gun, even with one bullet in it. But in this case, they figure they will use one of their own members. The reason is, is because if the cop pulls the trigger, and no bullet is fired, if it's a real victim the gang will still have to kill the person to keep them quiet. If the person is, killed and then a body later found, the undercover cop could be a witness to that killing. So by having a fake blood in, with one of their own members, and just pretending to get rid of the hostage, after the blood in is completed, the new recruit will be fooled into thinking he passed a real blood in test, but the gang does not have to worry about killing a real person, and being caught for it later, if the cop is an undercover. But I was told by readers that it does not make sense for a gang to use a fake hostage, and that the gang would use a real one, and frame the new recruit for murder if necessary. Do you think that's true though? I mean the cop knows who one of the gang members is personally, and if that cop would turn him in for murder of the victim, that would suck for him. Where as if no murder is committed, the cop does not have anything to turn him in for, should he choose not to do the blood in. But I was told it does not make sense, and gangs commit real murders and do not realistically bother with fake staged ones. What do you think?
