> Why can't there be a federal law enforcement division that works on behalf of federal agencies with a need?

This may be efficient, but we should consider whether inefficiency may actually be a feature. Each individual enforcement arm is weaker, less easily coordinated with others, and less likely to be commandeered in pursuit of overarching federal goals. A common federal law enforcement entity could come to disconcertingly resemble a domestically deployed military.
