In an ideal world, the little scrote should be locked up, one attempt made to reform him and if that fails, he goes away for longer. The rest of us stay within the rules that form a relatively civilised society, so if you step outside those boundaries, you deserve everything you get. I'm sick to death of hearing about criminals getting no more than a slap on the wrist, because some do-gooder or smug lawyer stands up in court and starts bleating about his human rights.
We're not living in an ideal world unfortunately, on this topic and others, but to be quite blunt, I would not be losing any sleep if one of these little scumbags - who let's face it, think they are above the law anyway - gets a taste of 'community justice' as a result of his face being plastered on buses and billboards all over town. If that then enables the members of that community to live their lives in relative peace, so be it ...
