Legally, sentences should be imposed, primarily, to reflect the level of criminality involved rather than the consequences of the criminal act.
However, there is a process to follow in sentencing offender which includes looking at the sentencing guidelines for the offence and paying due heed to the five purposes of sentencing:
-the punishment of offenders;
-the reduction of crime (which includes general deterrence;
-the reform and rehabilitation of offenders;
-the protection of the public;
-the making of reparation by offenders to persons affected by their offences
When setting the sentence (or type of sentence), the court must take into account factors such as
?the seriousness of the offence
?the offender?s previous convictions;
?aggravating factors e.g. particularly vulnerable victim;
?mitigating factors
?personal mitigation
?plea of guilty
I think it is the emphasis on this sentence as a deterrent sentence first and foremost which makes it unplatable and too long.
The judge has used an 18 year old of impeccable character who admitted his responsibility for a grossly reckless act (thus saving police alot of time) which, fortuitously, did not result in injury, to send a message to others who may do the same.
This boy had only just turned 18 (significant for sentencing purposes) at the ttime of the incident and was involved in a dismally poorly policed demonstration where chaos reigned.
Prison, perhaps, for what might have appened. Two and half years? over the top.
