Sigh @Dappy777 .
When the Conservatives left power, they'd promised to increase prison places and failed to. In fact by the time they left office it was at over 99% capacity.
It's not a "left v right" thing. I do agree with you on your concerns on rehabilitation programmes. But as has been explained to me by the probation service, the job of probation is to assess risk of reoffending. Not to placate victims, sadly. And I am a victim, hence my personal experience.
If we don't believe these kinds of offenders can be rehabilitated, and I share your doubts, then we need much larger prisons. And taxes need to rise for that.
But we also need to recognise that whether or not this offender was deported is a separate question and his immigration status, via Italy it seems, is complex. Also deporting a violent offender doesn't solve an issue, it just moves it.
I just wish all the people up in arms at violent immigrants were as bothered about British men who commit VAWG, and there are an awful lot of them too.
