Burchett v. State, 172 N.E. 555 (Ct. App. Ohio 1930)
“The possibility of identifying a bullet that has been fired with the firearm from which it was projected is now receiving intensive study by engineers. The Engineers’ Foundation of New York is promoting such an investigation by Major Gunther, a professor of Stevens Institute of Technology, who has a highly technical paper on the subject in Mechanical Engineering for February, 1930. The new science, if it be a science, for want of a better name, is known as interior ballistics Elsewhere Prof. Gunther has said:
‘Ballistics now is in the same stage that finger printing was in the days when data on the probability of duplication was being accumulated. And it is fully as promising. Building up faith in the evidence obtainable from ballistics is a matter of accumulating *469 data over a period of time. I do not say positively that there are not two identical gun **557 barrels in the world, but I have yet to find them.’”
