It is traditional to have a clearance before landing. So the next question has to be, was going around sensible? A go-around shouldn't be considered a risky manoeuvre, just inconvenient from a schedule point of view. Furthermore, if there were a few more go-arounds we might have a few more intact aircraft - for a variety of reasons. The real question has to be, who are the clowns kicking up the stink? These are the real idiots who should be dealt with. It is beholden upon every pilot to perform a go-around if they believe a safe landing cannot be made.
