The friendly British bobbies, created by Robert Peel in 1829, were the first professional police force, copied by cities around the world.  The men on patrol became known popularly as "peelers" or "bobbies." The former nickname faded away and the moniker "bobbies" caught on.  Much of which Peel created lives on today as well. He believed that the police force should operate from a centrally located headquarters which should be easily accessible to the public. Of prime importance would be recruitment, selection and training of the police force. All "bobbies" would be dressed in proper uniforms and be paid a full-time weekly wage.

When visiting London travelers will certainly feel safe.  Bobbies are generally friendly and never far away.
