Roberts replaced Rehnquist.
Rehnquist is the effing idiot who wrote a decision that makes it so difficult to convict a police officer that it will never happen, or happen only in extreme circumstances:

The courts 1989 ruling in Graham v. Connor spelled out a legal standard that shaped how juries weigh evidence when considering charges of excessive force.
The question is whether the officers actions are objectively reasonable in light of the facts and circumstances confronting them, without regard to their underlying intent or motivation, Chief Justice William Rehnquist wrote in the opinion.
The reasonableness of a particular use of force must be judged from the perspective of a reasonable officer on the scene, rather than with the 20/20 vision of hindsight, Rehnquist explained in the opinion. The calculus of reasonableness must embody allowance for the fact that police officers are often forced to make split-second judgments in circumstances that are tense, uncertain, and rapidly evolving about the amount of force that is necessary in a particular situation.
The word objective is important. It means a jury cant take into account an officers subjective beliefs, including his prejudices and biases, when deciding if his actions were reasonable or not.

Anyone who knows anything about attribution theory will tell you what a foolish decision this is.
This debacle can be laid squarely at the feet of conservatives.
