Britain has some of the most restrictive controls on firearms of any nation on earth. Inspector Colin Greenwood wrote the first academic study of gun control in England and Wales, at Cambridge University, in 1972. He found that registration of guns and the licensing of guns had no effect on crime. From A Study of Armed Crime and Firearms Control in England and Wales . . .
How, then, should policy on firearms controls be affected by the facts produced? The system of registering all firearms to which Section I applies as well as licensing the individual takes up a large part of the police time involved and causes a great deal of trouble and inconvenience.
