Felons' interests count heavier than that of their victims

Who do they think they are? Is Germany a sovereign state?

As a soveriegn state didn't Germany make this EU thing part of German law

Now we get forced to soften up national laws that guaranteed protection from dangerous felons and have to release these people into society again.

Are these not new laws that were introduced after the agreement to follow the EU courts laws.
As I said earlier the fault lies with the initial sentences by German judges in German courts under German law.

The British people (a good majority IMHO) still await a referendum as to whether we (the UK) should remain a member of the EU and your original post is a shining example as to why they're concerned.

The only issue the Brits have in this case is the questions about life=life ruling. Which will stand as many other EU countries have the same well established law. If by some strange quirk of circumstances that legal option should be overturned then there is still the minimum term which is open so there is nothing to stop a judge from giving 3 life terms with each of a minimum of 40 years to be served consecutive.
If by some miracle a nonce lasts those 120 years in prison then all it needs is a good doctor to section them all nice and legal for the rest of their natural.
