When ATC vectors you around traffic in IMC or clears you below LSALT "on radar terrain" you are in many ways trusting the professional competency of that controller, when a ground crew member closes your cargo door you are trusting a degree of competency so why should ATC have to look out the window to check wether or not the pilot has achieved the absolute minimum level of competency in lining up on the runway instead of the taxiway?
