The Horniman has stated that the Chicken event was a mistake and won't be repeated. Whilst obviously deeply traumatic for many of you, it was a one-off. They have stated that they don't want that sort of event again, and explained quite reasonably, I think, why they need a new licence. Why can they not be given the benefit of the doubt?
By being so strongly anti the licence change the local residents are taking the short view, without looking at the long view of the future of the museum and the benefit to the area as a whole.
