We declined it because a month before almost 200 people died doing that. It was a safe approach but it was too close to the tragedy and out of respect for the dead we didn't want to show how it should have been done. We respected the crew that died that day and proving it could be done easily didn't seem appropriate. It took 5 minutes and we had an ILS approach at night.
Most of the passengers probably knew what happened the month before and would have preferred what we did. Flying into Cali dozens of times that was the only time I was offered a straight in approach.
