In People v. Allah (71 N.Y.2d 830, 522 N.E.2d 1029, 527 N.Y.S.2d 731 [1988]), defendant and his companion, who were both armed with guns, engaged in a heated argument with two other men (named Scott and Greene). During the course of the argument, defendant intentionally aided his companion by shooting Greene in the back when Greene tried to stop defendant's companion from shooting Scott. Because defendant shot Greene, defendant's companion was able to shoot and kill Scott. Based on the circumstances of the case, this Court found that defendant shared a "community of purpose" with his companion.
