"This isn't a British colony anymore..." ignores the fact that police are *required* to be competent in English ...
In response to the reddie, I'd say that this is irrelevant. The fact that policemen should be able to have competency in English has no relevance to the fact that the court/arbitration/inquest may choose to conduct its deliberation in the native language of the majority of the population here including the policemen who is under the spotlight.
I think that we're very lucky that the government/local people have the courtesy to maintain a very reasonable level of English throughout the territory.
