It doesn't help to fight crime to put people in prison who are innocent.
Nobody wants a judge to be subject to the political whim of the moment.
We are selected, but I grew up in California and in San Francisco and there was a system of electing judges.
But once the person is selected, at that point that person is independent.
At least there's a political input, but when you put on the robe, at that point the politics is over.
Judges are appointed often through the political process.
