The Lord Mayor has commented on this and wants it removed. Its not exactly on public display up on the first floor of the city hall. If the council debate it and decide it should go then the museum next door may be the best place, then its will be on public display.
I understand Thomas Picton treated his slaves like shit apparently, and I believe killed one.
George Washington also had a similar reputation with his slaves, and used to break up families by sending individual members to different distant parts. Be interesting if they tried to pull his statues down in USA
