[IQunder130]

This does raise the question of how many cases are actually up in the air at all. One would think that given the IQ distribution of criminals a majority of cases involving arrests are quite open and shut, with suspects usually being caught either red handed or after not covering their tracks at all.

A justice system optimized for public safety will err on the side of putting aggressive, anti-social individuals behind bars rather than making absolutely sure they really did do the thing most of them were caught doing. Public safety is therefore orthogonal or even somewhat opposed to the pursuit of truth.
