Isn't it obvious? Every rock Mueller turns over yields multiple slimy critters who slither out. Each of them must be investigated. So will the investigations into stable boy last forever? Longer than the Afghanistan war at the very least? Where do you stop when the evidence keeps piling up...the leads keep growing geometrically and the scope grows wider automatically? How do you stop in the middle? How do you know if it is the middle or still the beginning of an endless exploration into evil degradation treason collusion conspiracy? You don't take a half-baked cake out of the oven. The size of this cake keeps growing and growing and growing and so one wonders if it will ever be ready to serve? :(
