Everywhere in the US is a high enough crime area that people need the police to feel safe.
But very close to me (like 15 min of walking), there are major armed crimes happening. There are enough guns and people willing to use them in this country that it is just not safe without the police.
There are many reasons for this, I probably agree with most of them, but until they are all solved we need the police.
I grew up in Norway, did not feel like this there at all. Of course crime does still exist, but I would not care how far it was to my local police station.
Also lived in the UK, felt very safe compared to the US.
