The Henry guideline judgment for armed robbery applies to aiders and abettors, not only to those who commit the substantive offence. A driver who transports co-offenders to and from an armed robbery, knowing a weapon will be used, is a principal in the second degree whose objective criminality is to be assessed in the context of the armed robbery offence, and the form of the charge (aid and abet rather than substantive offence) does not automatically diminish that assessment. Youth and first offender status cannot be permitted to overwhelm the objective gravity of serious armed robbery offences requiring significant sentences of full-time custody with a general deterrence component.
