Connor's Flawed Logic / Japanese Supremacy
He says that "in Japan, criminals expect to be caught," because convictions run about 90% whereas in the USA it is much lower. But that doesn't prove that the people who are convicted are guilty. I think the book Freakonomics and the documentary talk about how Japanese police just ignore crimes they can't solve and say they aren't crimes. They find a dead hooker with her throat slit in an alley and write it up as a suicide. They find a dead sumo wrestler beaten and burnt with cigarettes and say it's an accidental death. So Connor's deduction is bogus. The fact they claim higher convictions and more murders being solved doesn't prove anything. They pick which cases to investigate and hide their murder rate under bogus suicides and accidental deaths. This is well documented. Yakuza crime bosses openly dine with politicians and come to America for transplants, jumping ahead of other people in line with help from our government. Japanese criminals hardly fear being caught. They are celebrities and public heroes.
Another example. He says that Nakamoto didn't ask for him to be called in on the case because they are "formally protesting" his involvement. That is so dumb it hardly needs to be explained; it amounts to saying "I know they're not lying because they say they're telling the truth." Eddie is a liar. His very first interaction with Connor has him claiming he heard about the murder but he doesn't mention that his girlfriend was killed. Then he denies he knew Cheryl. Then he says he knew OF her. Then when Connor corners him and says he's putting her up at the Imperial Arms he admits that he brought her to the party but HE had nothing to do with her death. Why would Connor trust Nakamoto any more than Eddie if he has to twist his arm to get the whole truth?
Another silly argument in the movie is when Jingo says "in Japan," they would have done it right and "the ghost would have stayed hidden." But they could have easily hidden the ghost by simply cutting the clock out of the frame and using stills of the empty room from that disc or any other one! So she's arrogantly saying the Japanese are perfect and so smart they no doubt would've done the job flawlessly - had they only been facing Japan's infallible totally honest police and 90% conviction legal system, of course. Ha. But they were too stupid to see they could have doctored the disc much easier and better and saved hours of work and made it perfect.
Another flaw with that logic is that you can see the guy who had sex with Cheryl had curly brown hair, unlike Eddie who had straight black hair. So they couldn't even do that right, either. Maybe they could have fixed his hair instead of wasting time digitally removing him. Edit together footage of Eddie walking in to match the senator. So much for Japanese perfection. They're as flawed as anyone else.
