Narrative:
Twin cessna (X) was landing runway 25R. Seminole (Y) was departing runway 25R. A developmental controller on a skills check was working local control 2 with an fpl plugged in override and a supervisor monitoring. The seminole was slow departing due to a B737 that had just departed intersecting runway 30. When the twin cessna was on short final, the supervisor asked 'how much separation do you need?' the developmental replied '4500 ft' and told the twin cessna to 'go around.' the twin cessna pilot asked 'why? He's airborne.' the developmental keyed his microphone but just stuttered. The twin cessna pilot said 'you're breaking up' and proceeded to land without a clearance. The supervisor asked everyone present if we agreed that minimum separation existed. I did not reply because I felt intimidated. The incident was not reported.

Title: LGB CTLR OBSERVES TWR CERTIFICATION INCIDENT BTWN TRAINEE, INSTRUCTOR AND SUPVR, WHEN AN ACFT ON SHORT FINAL LANDS WITHOUT CLRNC IN CONFLICT WITH ANOTHER ACFT DEPARTS FROM THE SAME RWY. RPTR FEELS INTIMIDATED BY SUPVR'S RESPONSE TO INCIDENT.
Narrative: TWIN CESSNA (X) WAS LNDG RWY 25R. SEMINOLE (Y) WAS DEPARTING RWY 25R. A DEVELOPMENTAL CTLR ON A SKILLS CHK WAS WORKING LCL CTL 2 WITH AN FPL PLUGGED IN OVERRIDE AND A SUPVR MONITORING. THE SEMINOLE WAS SLOW DEPARTING DUE TO A B737 THAT HAD JUST DEPARTED INTERSECTING RWY 30. WHEN THE TWIN CESSNA WAS ON SHORT FINAL, THE SUPVR ASKED 'HOW MUCH SEPARATION DO YOU NEED?' THE DEVELOPMENTAL REPLIED '4500 FT' AND TOLD THE TWIN CESSNA TO 'GO AROUND.' THE TWIN CESSNA PLT ASKED 'WHY? HE'S AIRBORNE.' THE DEVELOPMENTAL KEYED HIS MIKE BUT JUST STUTTERED. THE TWIN CESSNA PLT SAID 'YOU'RE BREAKING UP' AND PROCEEDED TO LAND WITHOUT A CLRNC. THE SUPVR ASKED EVERYONE PRESENT IF WE AGREED THAT MINIMUM SEPARATION EXISTED. I DID NOT REPLY BECAUSE I FELT INTIMIDATED. THE INCIDENT WAS NOT RPTED.
