People like to take things out of context. A communications director of all people should know this – so why even risk posting tweets mentioning knives etc, joke or not? I just don’t buy the argument that Twitter is a personal forum and therefore his comments should be seen as such. It is broadcast for the whole world to see. It’s exactly the sort of thing that will be picked up and exploited by those who don’t see eye to eye with you. Perception, not intent, is the only reality on the internet.
