Bigby only got involved after speaking to Elizabeth and Lara Croft, who asked him to involve himself. He may very well be staff, but the logic that staff would intentionally interfere does not apply to him.
The ones remaining are Luke Castellan, Elizabeth, and Lara Croft. Elizabeth was, I believe you agree, the most aggressive towards Diva. But Luke Castellan was among the first to reply to Leo Baskerville's statement and chime in that it seemed suspicious. Lara Croft avoided involving herself, but still weighed in with her opinions that the candlestick assault was relevant.
In my opinion, the most likely point in time staff would have gotten involved was right as a plausible suspect was identified. It would not necessarily be strategic to insist on an interrogation. But it would be strategic to help emphasis that the candlestick was relevant, as that piece of evidence all too easily could be brushed off.
Everyone else involved either argued against the candlestick, or became involved later, after Diva had already been violent.
