VIOLENCE - The abuse of force. That force which is employed against common right, against the laws, and against public liberty. In cases of robbery, in order to convict the accused, it is requisite to prove that the act was done with violence; but this violence is not confined to an actual assault of the person, by beating, knocking down, or forcibly wresting from him on the contrary, whatever goes to intimidate or overawe, by the apprehension of personal violence, or by fear of life, with a view to compel the delivery of propert equally falls within its limits. When an article is merely snatched, as by a sudden pull, even though a momentary force be exerted, it is not such violence as to constitute a robbery.

VIOLENTLY - This word was formerly supposed to be necessary in an indictment, in order to charge a robbery from the person, but it has been holden unnecessary. The words " feloniously and against the will," usually introduced in such indictments, seem to be sufficient. It is usual also to aver a putting in fear, though this does not seem to be requisite.
