Of course, there's still monetary benefit to the museum, London and Britain from people visiting to see them.

People who are travel to see the crown jewels are going whether or not this one is there with it.
Apparently, the Tower is not government property, but belongs to the Crown Estate.
(I suspect the British cannot return the Koh-i-Noor diamond because it's not government property, either.)
Historic reparations (beyond 100 years or so) fundamentally requires you to ignore the individual and treat people as being part of homogenous groups categorized according to some probably highly subjective traits. Its fundamentally evil.
Compare that to Nazi Germany, where reparations were paid in significant quantities, and kids in schools are still taught to be embarrassed by that section of their country's history. Whereas you get the sense that Britain is still, in some ways, proud of its rather ruthless and barbaric empire.
Well, it was a long time ago, so why bring up the atrocities now, eh? Thanks for the wealth, and here are a few meaningless pennies in aid. You can consider us your heroes now. /s
There also were payments to Poland, Greece and Yugoslavia.
Also, just in terms of numbers, the British empire was pretty insane in terms of the quantity of people it murdered, both directly and indirectly. The number is much higher than those murdered by the Nazis, even if it happened over a longer period. They should certainly be held accountable, at the very least.
When you say "the British should be held accountable" all those individuals are dead and gone. It's a bit Catholic to hold the children accountable for the sins of the father. Its unlikely my forefathers even had the vote at that time. So please explain how I'm accountable again?
Edit: It's clearly a subjective topic, but there are significant impacts felt the world over due to the British empire. I'm not sure you can say the same of Alexander the Great. People are directly and significantly affected to this day by the actions of the British. I guess the nature and extent of the impact would need to be decided by a court, but it'll always be an imperfect science. That doesn't mean it's unnecessary.
"Property is theft, therefore theft is property."
Basically the Nigerian federal government, the state government of Benin, and the descendants of the kings of Benin who originally owned the stolen Benin bronzes all think they should be the ones to whom the bronzes should be returned -- and in the case of the current king, he asserts they are his family's private property.
On top of that, there is a long track record of art being stolen from modern-day Nigerian museums and sold to other museums or collectors, and returning the bronzes just for them to be re-stolen does not benefit any of the parties involved.
