The UK's National Crime Agency is on a roll. It's taken a while for the successor to so many different organisations to get its act properly together, demonstrating the constant shuffling around of people and responsibilities detracts from their ability to do the job. The men and women of the NCA are a hard-working and bright bunch and recent results show that if they are left to their own devices, and given time to execute sensible plans, they do exactly as they are supposed to do: get convictions, often where they were apparently unlikely. One, yesterday, makes the point nicely.
