I heard of an incident where two jets on final approach got so close that the 2nd one had to be broken off by the watch manager who was working the approach radar position but transmitted on the tower frequency to give the instructions. The incident was reported to the Air Traffic Manager who then failed to report to the CAA or pursue any further action. The watch manager then reported to the air traffic manager that the initial reporter of the incident had attended work under the influence of alchohol. The reporting person was then suspended and subsequently resigned. So to me it is be carefull who reports what.
