Does it matter whether Barclays or some predecessor company was involved in the slave business? Even if the allegation is true, it happened over one hundred years ago. All the victims are dead. The estates of American slaves and other nineteenth-century poor people are unlikely to have heirs who can prove themselves to be legitimate heirs within some legal jurisdiction. There is obviously no living individual with a direct claim. The only crime without a statute of limitations is murder, right? If I were to allege that someone enslaved me for a period of time even twenty years ago, it would probably be thrown out of court. This case is about publicity, not money, and is even more deserving of dismissal.
