The old jokes are the best...

Dr Crippen (here) is referring to Ms Hewitt but it applies with much more force to Commissar Andy Kerr:

Stalin, Khrushchev and Brezhnev are travelling on a train. The train stops. Stalin leaves the compartment. When he comes back, he says:“It's all sorted - I've shot those responsible”.
Train doesn't move. So Khrushchev leaves the compartment. When he comes back he says 'problem solved - I've rehabilitated those responsible'.
Train still doesn't move. Finally, Brezhnev stands up.
'Well, what are YOU going to do?' say Stalin and Khrushchev.
'Easy', says Brezhnev, 'I'm going to pull the blinds down and PRETEND the train is moving'.
