Unfortunately, knowing the Finnish justice system, a "life sentence" usually means about 13 years in prison, not more.
True.
And not only that: Once he has served his "life sentence" of 13 years or so for killing 2 people and wounding several others, Finland probably cannot even deport the guy back to Morocco - because of the unwillingness of North African countries to take back their people.
So, sadly these host-country abusing killers and rapists from Africa and the Middle-East will always remain a plague for our countries and our taxpayers ...
