>What would happen if the owner was armed and harmed the police thinking that they were criminals?
A hefty prison sentence for illegal handling of firearms and attempted homicide would be my guess.
I was thinking of the police officers. Why risk your life for such a petty crime?
First time murder is typically gives around 12 years in Denmark.
Sentences are not added up. So yes, trying to shot a police officer will definitely get you decent sentence -- it's not hefty by American standards.
