I haven't lived in Bristol for decades, but I do remember Colston's slave trading being discussed on local radio in the early 90s, when the naming of Colston Hall and this statue were mentioned.
So I am surprised by the fact that in all that time since, there wasn't even a plaque placed by the statue mentioning slavery. Then hearing the current mayor explain his opposition to the statue, but offer some excuses for why he has achieved absolutely nothing about it in four years..... I guess my angle is that despite twittering by politicians and others about democratic processes, no such course of action seemed available, so chucking it in the river was justified.
