Smoking gun - sustany/dvg GitHub Wiki

The phrase smoking gun has widely been used to mean a discovered piece of evidence or fact that proves a theory or point. In law, the term is most often used to describe a piece of circumstantial evidence that will lead to a person�s conviction. The term arose from a time where smoke coming from a gun meant the gun was recently shot. So, if someone�s gun was smoking, that would be considered strong evidence of their shooting at something recently.�
