The US has a whole department that is supposed to police scientific fraud, the ORI. It was set up in the 70s after a series of fraudulent studies caught the attention of Congress. Unfortunately after a few failed prosecutions early in its history the ORI now does very little, only a handful of cases per year. Compared to the scale of the problem which is often measured in something like 50%+ or more of papers, it's just irrelevant. There is no "police department" you could staff up that'd be big enough to get a handle on this problem.
