Does the US Supreme Court write criminal laws?

Answer:
The US Supreme Court doesn't write any laws; that's the job of Congress, the Legislative Branch of government. The Court does interpret criminal laws to make sure they're constitutional and are applied properly, but only when the law is relevant to a case they're reviewing.
