I'm not really sure why so many people think the most reasonable explanation was that this guy was already known to the police before he entered the MK? I'm further confused why so many think he was a known wanted person and the police decided to do a "take down" during the dessert party? How many hardened wanted criminals are going to the MK and paying for the dessert party you think? I'm not saying it's impossible, but do we really think that any of the above scenarios are likely? Based on the story from the OP, is it more likely this person was a normal guest who got out of control while at the MK and had to be dealt with there? I know folks love a juicy crime story, but I think many are overthinking this situation.
