Mr. Eisenberg. Were there any negative results following the shooting of the revolver or automatic pistol?
Mr. Cunningham. None of those were negative results, but they were not run under the same conditions. By the way, with an automatic pistol you shouldn't expect to find any residues, for the same reason as with a rifle—the cartridge is chamber, and the boltface comes in right behind.
Mr. Eisenberg. Could you look at your notes for your first experiment, because as I recall there were some negative results on that.
Mr. Cunningham. The only negative results were on the 20 people who were run as a control and who had never fired a gun, and even for those people they all got positive reactions at least on one hand.
Mr. Eisenberg. I am talking about the first experiment now, not the second one.
Mr. Cunningham. The first experiment—yes; that was true. This test was a little bit different.
In other words, they were not just taking people from their work. These people had washed their hands.
Mr. Eisenberg. In other words, their hands were cleaned before they fired the weapon?
Mr. Cunningham. Yes.
Mr. Eisenberg. But then some of them fired a revolver and still didn't get a residue, as I remember your testimony?
