What can you tell me about the Federal Judiciary System in the US?
Well I can tell you to start that it's one of the three co-equal branches of the federal government, something I remember learning in high school.
What kind of laws are made there? All of them or ...?
Not quite, the federal judiciary determines the legality of the laws, but the laws themselves are made elsewhere in Congress.
Ohhh interesting... So is this the level of government that the laws are enforced? 
Well the laws can be enforced in state and local courts as well, and the highest disputes regarding the legality of laws and cases reach the Supreme Court.
