Next season better not be about another murder.
I'm hoping for something about white-collar crime in the financial sector. It probably won't ignite the masses the way that this season has, but I think it's something that would be well served by this format.
White collar crimes aren't interesting, at all, and have so few witnesses or conflicting testimony that you'd barely be able to make more than an episode or two about it. "He siphoned $2.7M over the course of 8 years. Here are the statements linking him to the Cayman island account". Or its dumb, insider trading crap that is hard to prove, so prosecutors pick away at "making false statements to prosecutors", like the Martha Stewart case.
I'd really like to see SK built another case, one without Adnan. I know the case against Adnan is circumstantial and based on witness testimony but it's more than on any other case you could've built.
Generally, we (as a society) don't give life without parole to minors on just circumstantial evidence, even if it is the most plausible.
Without Jay's plea-bargain-driven statements, there really isn't anything resembling a case against Adnan.
