Having the opportunity to finish the game. I like to ask how you interpret the killer's trap for Nikki in the end? It is never explained how she will be framed and the so-called recording that will show instead she is the perpetrator. Huh?

I think what the recording will show is that she killed a man with an empty pistol and on top of that he was not the killer they were looking for. This will not frame her as the killer but it should be bad advertisement for FBI and so she would loose her job
