"this difference is largely due to the differences in the size of the respective populations. The panel report notes that the U.S. has a population about five times the size of the UK, but there have been fewer than twice the number of people extradited to the U.S. than to the UK."
What? That seems extremely nonsensical to me.
Wouldn't one reasonably expect the number of extradition requests to a country to be proportional to the number of people in that country, not the number of people in the country doing the extraditing?
