It means you are classified dangerous and not curable. I guess this is the same in England. So there must be something seriously wrong with the guy. Mother doesn't see that obviously.
The indefinite sentences were abolished in 2012 because they were being overused. They just didn't retroactively eliminate the existing sentences and the Parole Board has taken forever to sort through the problem.
In 2016 the head of the Parole Board said they wanted to reduce the number of IPP sentences to 1,500 by 2020 [1], but you know... Tories happened.

The authorities also don't want to be held to account for traumatising these people and any crimes they subsequently commit. 12 years is a murder tier stint, so pretty much all of them should just be released. However releasing a lot of dangerous people looks bad even if it's morally justified.
No it doesn't. It means you've got some sort of mental issue. Curable or not. TBS is more focused on treating the underlying issue instead of simple punishment or rehabilitation.
TBS also doesn't mean you're "incurable" That's just flat-out wrong. The entire point of TBS is to treat (i.e. cure) people.
Everything about your comment is wrong. There's a reason IPP got shot down for human rights violations and TBS hasn't been: because it's fundamentally different.
