Shooting pigeons in city centres

We're in central London where the feral pigeons are a real menace.The birds have found all sorts of places to roost around a busy shopping centre. They're next to the shops, in the car park and on the roof. Roy Lupton is going in with his Air Arms sub 12ft lb air rifle to try and knock a few off their perch.
