Re: Strange world
You need to remember that there's a lot more to sentencing than meets the eye. Obviously you also get inconsistency between different judges. But still better that than giving them no discretion, or even worse things like 3 strikes and you get life policies.
In his case he had previous convictions - for the bomb hoax and (an unspecified by the article) previous breach of the Computer Misuse act. That'll add some time. Sometimes quite a lot, in that judges can be very lenient for first offences.
But also another aggravating factor will have been that this offence was a direct response to his sentence for a previous crime (the hoax bomb threat). And that sort of thing really pisses off judges. So I suspect a point was being made.
