The U.S. has the same system, derived directly from English jurisprudence. But we also enjoy freedom of association, freedom of speech, and freedom of opinion. The courts and the legal system are constrained, but not the individual, and press freedom is part of individual freedom.
Another concept people don't seem to fully understand is "innocent until proven guilty." It doesn't mean that a person who (for example) stabs another person to death is "innocent" of the crime until it's been proven in a court of law, in the sense that "he didn't do it." It means that he's presumed innocent within the legal system until his complicity has been properly adjudicated. No such presumption can change the actual facts. He either did it, or he didn't.
