Orwell advises against using the vague language found in the Independent’s story about the dead MI6 guy, saying Gareth Williams worked for an MI6 division that “eavesdrops on global communications.”
Better to have said “international calls and email messages,” or “between the UK and other countries.” “Global,” though often used, is so vague as to be meaningless.
The Independent (link and excerpt, below) also seems in a hurry to shoot down, based on no evidence either way, any suggestion the agent’s murder might be work-related:
The reality, however, is likely to be more mundane. Sources within the murder inquiry led by the Metropolitan Police’s Homicide and Serious Crime Command insisted that “the suggestion there are terrorism or national security links to this case is pretty low down the list of probabilities”. They are believed to be concentrating on Mr Williams’ private life.
