So this man kills FIVE people in 1978 and goes into a mental institution.

In 1994 (only 16 years later) he is allowed out on the streets. Only about 3 years for each murder.
In 2013 he is arrested again for possessing firearms and making a bomb and is now under trial.
Surely even if he was mentally ill when he killed those 5 people in 1978 he should not have been let out so quickly.
Even if he no longer had those mental problems surely he should have then continued his "prison" sentence in a normal prison.
People like Dennis Nilson and the Yorkshire Ripper were mentally unbalanced when they committed their murders, and they are still in prison.
So why was this man let out so "early".
