The civil rights era was hard on juries. Lots of crimes became federal and were moved out of local jurisdictions. While its true that racist jurors were willing to let obviously guilty men go free, the cure was worse than the disease.
I despise hate crime laws for the same reason.
Two people in the US are needed to substantially reform federal judicial abuses, the chairmen of the house and senate judiciary committees.
If both of them are conservatives, with a conservative POTUS, there is hopefully going to be a lot of judicial reform.
To start with, the structural organization of the federal courts needs rearranging in several ways, such as dividing the 9th Circuit and making a more orderly process of the 8,000 or so appeals to the SCOTUS every year, which can only handle a few dozen cases.
Appeals of local and state issues that have been federalized, are often utterly petty and redundant. They need to have divined outcomes so substantially similar cases don’t clog the federal courts year after year. (The best example being the Alaska public school case of “Bong Hits for Jesus”, that has made it to, and been accepted by, the SCOTUS, twice!)
Next, state death penalty appeals can be easily streamlined without impairing any justice at all. Just declaring that states are competent to carry out executions without challenge by itself would half the time of such appeals.
