This thread is most likely off topic, but since Norway is my home country and since some posts show that you know very little about Norway, I hope I may be allowed to explain.
Norwegian police are not carrying firearms on a daily basis, but have weapons in the cars. When a distress signal like this comes in, they arm themselves. Also in this case police from other towns came heavily armed.
Even if the criminal carried a bow and arrows( the police have not said if it was a compound bow or other type)
We do not yet know if the bow was used in the killing of 5 people. They say other weapons were used also.
We know that one person was wounded in the shoulder by an arrow.
It will be a few days befor we know all the details.
Bow and arrow is not forbidden in Norway, but bow hunting is.
To say that the Norwegian people do not have much freedom is nonsens in the first degree.
Yes, we have high taxes, but a lot of benefits that many countries lack.
Just to mention a couple, free hospital no matter what kind of surgery you may need. You just pay a small amount for medicines. If you get sick full wages for a year. Schools are free . I could mention many things.
