Clearly under the control of the legal community. One needs to be a lawyer before one can become a judge, and properly so. Nowhere is amorality and objectivity more necessary than in a judge. He is the last resort for many of us. The Executive Branch.
Prosecutors again are lawyers and complete objectivity is required here.
The Legislative Branch. I contend it's unhealthy to have ANY interest with that much influence in this country. To have them also make the rules is just too much. Fox guarding the henhouse and all that. Lawyers are amoral by definition and necessity, and as such should not be making the rules for the rest of society to live by.
