“It must follow that, in order to achieve a conviction, the prosecution would have to produce sufficient evidence to make the jury sure that, at the time the conspiracy to commit robbery was hatched, a defendant knew that – as part of the plan – a firearm loaded with live rounds, was to be carried to the scene of the intended robbery and, further, that the defendant (again, at the time he joined in the agreement to rob) intended that the firearm should be used to kill [Mr Samma] if he resisted the robbers.”
“That, in turn, requires reliable evidence of identification upon which the jury could safely act in order to identify a defendant as being present at the scene of the robbery and shooting, whether or not identifiable as the gunman. Such identification evidence might, depending on the jury’s view, be capable of providing a basis for concluding that the defendant had the necessary conditional intent that RS should be shot dead and, further, that an attempt to murder him was within the scope of the plan to which the defendant had given his assent and intentional support (borrowing the words used at [94] of [Jogee].”
“whether they are sure that D1’s act was within the scope of the joint venture, that is, whether D2 expressly or tacitly agreed to a plan which included D1 going as far as he did and committing crime B if the occasion arose”
“If the jury is satisfied that there was an agreed common purpose to commit crime A, and if it is satisfied also that D2 must have foreseen that, in the course of committing crime A, D1 might well commit crime B, it may in appropriate cases be justified in drawing the conclusion that D2 had the necessary conditional intent that crime B should be committed, if the occasion arose; or in other words that it was within the scope of the plan to which D gave his assent and intentional support. But that will be a question of fact for the jury in all the circumstances.”
