I completely agree that burning an effigy of the Grenfell tower (with people, including a baby, carefully drawn on it -what the fuck) is twisted and sick, disturbing and deeply offensive. But (prepares to be flamed) in a week where the media has been full of the cuts in funding to policing, the fact that there have been 4 stabbings in South London in almost as many days with no real solution currently in sight, we are being repeatedly told that police have to prioritize where to focus their resources now; ie burglaries are unlikely to be attended any more - no I don't think putting a cardboard box on a bonfire is what the police should be focusing on. Yes these people are disgusting but we have always had foul, offensive elements in our society. Whilst I find these people and their actions repulsive no I do not think this case is where police should be chanelling resources.
To make another point (and whilst this does not excuse this repulsive act)British Bonfire Night celebrations originate from a similar place of bad taste. A Guy is an effigy of a person, to be burnt in the flames, to symbolize Guy Fawkes burning,and the explosion he set in the Houses of Parliament. Even today, if I built an effigy of Simon Cowell, or Donald Trump, or Piers Morgan, and burnt it on a bonfire on Bonfire night I would do so to claps and cheers. Whilst offensively done, the burning of an effigy of Grenfell Tower is only an extension of that poor level of taste.
