Mr. Belin. Suppose I were to wash my hands between the time I fired it and the time you took the paraffin test?
Mr. Barnes. It would hurt the test.
Mr. Belin. It would cut down the test?
Mr. Barnes. Yes.
Mr. Belin. Now if I were firing it, would it necessarily show on both hands? Suppose I were right-handed?
Mr. Barnes. Depends on the location of your left hand.
Mr. Belin. Well, generally from your experience, is there any particular location for a right-handed person to keep his hand when he is firing a pistol?
Mr. Barnes. Police officers are taught to keep their left hand near the pistol handle.
Mr. Belin. As an element of controlling it?
Mr. Barnes. As an element of controlling, and also an element which, if you should get wounded in your right shoulder, you would have the left hand to take the gun.
