Britain, Ireland, Norway, Iceland and New Zealand, officers are unarmed when they are on patrol. Police are only equipped with firearms in special circumstances. It's a strategy that seems to work surprisingly well for these countries. Police officers there have saved lives because they were unable to shoot.
Countries such as Ireland, Iceland, NZL, and Norway are in general peaceful countries, and it will be OK, even if the cops are not armed. But you can't apply the same logic in the United States, and say that policemen patrolling high crime areas there should go unarmed.
And at least in the case of Norway, it didn't worked out that well. Anders Behring Breivik was able to massacre close to 100 people, as the cops who were present were not armed. If some one had a fire-arm with him, then Breivik would have been taken out before killing more than 10 people.
ISIS on the other hand is religious fanatics that's the only difference
