Can't they do that?
Doesn't the U.K. have the option of "life without the possibility of parole"?
Because that's what he should get. And if that's not available, they need to shoot him. Swift, severe and certain.
When someone is sentenced to life in England and Wales, they have a minimum tarrif set by the judge which must be served before they’re eligable for parole. Generally speaking, you’d have to be a serial killer, a child killer or a cop killer to get a whole life tarriff. Your average common or garden murder on average gets a 15 year minimum tarriff until they’re eligable for parole.
