Occasional Tour Caddy
Not diplomatic corps more like Ex Royal Marine. But that being said I'm just not arrogant enough to think it's OK to act like a big man and accuse people of cheating without proof. Especially when that accusation could have knock on effects for the rest of the society causing unnecessary issues.
Get the proof first, then be as direct as you want. Going into battle without true facts and armed only with arrogance is a sure way to lose.
