I would much rather pass accurate and useful information briefly than have to explain myself in the Ops Room or Court. Ultimately, I don't have the training to ensure that a breach of the rules would actually diminish the risk of accident

It is usually more clear cut than that if there is a flight safety issue.
Below is a quote from the airprox board following a recent incident.
The M/L pilot displayed commendable presence of mind in following the A/G Operator’s instructions to stop climbing. The A/G Operator acted outwith his responsibilities and authority and in doing so prevented an even more serious occurrence, actions for which he is highly commended by the Board.
