Grier v. State

1. While, to constitute the offense of riot, there must be not only a common intent on the part of the two or more persons to do an unlawful act of violence or some other act in a violent and tumultuous manner, and also concert of action in furtherance of such intent, yet this does not mean that the evidence must show any previous plot or conspiracy on the part of the rioters. Both a common intent and concert of action may be inferred from the manner in which the unlawful act of violence is committed. Coney v. State, 113 Ga. 1060 (30 S. E 425) ; Jemley v. State, 121 Ga 346 (49 S. E. 292).
