Editor's Note: Since the Scientific Crime Detection Laboratory of Northwestern University, the Director of which is Editor of the Police Science Section of this JOURNAL, came into being as a direct result of the so-called Valentine Day Massacre which occurred in Chicago on February 14, 1929, a crime noteworthy for its speed of execution and the number of victims involved, both of which were made possible through the employment of the so-called "sub-machine gun," it seems quite fitting that an article exhaustively describing this weapon should appear in the section which he edits. Mr. Sharpe, as a perusal of his paper will show, is quite familiar with the history of the Thompson gun from its inception over ten years ago up to the present time. Persons interested in informing themselves upon the mechanism, function, and uses of this weapon, will find his contribution a most welcome one.
