Are we fucking with sofas again?

This is one of my dystopian thriller elements: If the police can't find the culprit of a high-profile crime, then they find someone, plant an orgy of evidence and railroad him into capital punishment or life in a supermax. Just to show that the long arm of the law always wins.

Doing a for-real investigation and just disappearing / killing off any likely suspects is optional, depending on how vengeful the elites feel about it.
