Is the Ethics and Anti-Corruption Commission suited to fight corruption?

This week the United States Justice Department gave a sterling example of how corruption ought to be fought: by meticulously investigating suspects then initiating prosecution.

There was little political theatre in the investigations of Fifa bosses and the former Speaker of the House of Representatives, Dennis Hastert. I bring these examples not to merely highlight US superiority in its dealings with graft, but to remind us that corruption can be tackled as a matter of law enforcement.
