In my story, what happens is that a gang is recruiting a new member and they give him a 'blood in'. It's a police term for when a new potential recruit, has to spill the blood of another person to prove their worth to the gang. However, the gang is cautious and they want to make sure that they are not recruiting a new member who will turn out to be an undercover cop, or someone who cannot be trusted, or something like that. So what they do with the new member, is that they have him shoot a tied up hostage, who has a hood over her head so she cannot identify anyone's faces. They are also all wearing gloves the entire time careful not to get any prints on the scene. However, the hostage is working with the gang and is just posing as a hostage. The gun that that the new recruit will be given is a fake prop gun, so no real weapon is used. However, a cop who is on patrol in an unmarked car, spotted something suspicious about the gang members, while they were on the way to the blood in, and discretely followed them. He sees that a kidnap victim may be killed so he busts in and rescues her. He manages to arrest one of them in the process and the rest get away as he tries to protect her, taking away the prop gun in the process. Afterwords the fake hostage is being questioned by police as to what happened, and since she was in on it, she doesn't tell them anything. She just keeps telling the police she doesn't wish to press charges. That's all she says, and stays quiet otherwise. However, readers have been telling me they do not understand her behavior after the blood in. They said that it would make sense for her to have a story made up and ready to go, to get the suspect off, like saying she hooked up with a bunch of guys from a party that night and did not get their names. No kidnapping took place, and the cop misunderstood, she would say. But I do not understand why readers think that. It makes sense that she would lie as a last resort to get the suspect off, if they were going ahead with charges and all. But the readers say she would make up a story right away. The problem with that though, is that if the police manage to find any little thing in her lie, that wouldn't gel, or anything that could be used against her, it might. By acting traumatized from the hostage experience, and saying she doesn't want to get involved further or press charges, doesn't that make more sense? Even though lying can make the suspect look innocent right away, it can also have something in that may be used against you and you wouldn't see it. The readers said that if she keeps quiet, she makes herself out to be a suspect cause it's suspicious. But isn't acting suspicious better than lying, which will probably but work, but could backfire if it's not 100% perfect? What do you think?
