Yes. Thunderchild, that's the wayLOL. And while we're at it, we'll jail every witness to a crime who doesn't name the perpetrator who is known to them ! There's a snag or two. It overrides the principle that no man can be forced to incriminate himself, in that if he can be forced to incriminate someone else there's no reason why he shouldn't be forced to confess to any accusation made against him alone.It overrides the basic right to silence, too
It also appears to make all witnesses, or all persons, present at the scene guilty by mere presence. What happens otherwise, in this case, if one of the three does not know the others but is a complete stranger who, say, has taken a lift ?
In the instant case it's not murder, as the mens rea for murder is not present, and it won't be manslaughter because that's why we have causing death by dangerous driving. (That offence was introduced because juries were refusing to convict of manslaughter, yet that's what 'death dangerous' really is, strictly speaking )
And apart from that,if we could charge that way, you'd have to find nine others on a jury who would agree with you.'Jury equity' would prevail, whatever the law said,and there'd be an acquittal !
