pierre , my first sergent , wanted something a bit more challenging than being in my uniformed section so he brow beat his friend david into training him up for plain cloths , but this was his first probationary outing into the real world , and he forgot two very basic points , one never go to a gunfight with only a knife ( he had not yet received permission to carry a concealed weapon ) , and two let the dog see the bone , ie james see sydney , and he instictively lunged towards the gunman completely blocking jamess view of him .
