A good friend explained to me a couple of years ago that the FBI has for a few years required a 4-yr degree for all entrants. So no more street savvy types such as you might still get in local LEO. Now, take into account that the majority of those degrees will be Law or Criminal Justice and consider the schools that provide such and you get the idea. McCabe is Duke for instance.
