Since long USA has had a more difficult and insecure society to handle. And they have handled it by NYC major Rudy Giuliani's zero tolerance model, for example, something that has never came up for debate in Sweden.
We also lack the energy and the kind of group-thinking "on steroids" that quickly made Singapore the cleanest.
So when it comes to ”decency”, un-extreme and pragmatic Europe walk in its own pace in the middle of the race.
The historically calm swedish society is the base for our softness on crime. You can definitely call it unswedish – ”in a negative way”, this time... - to wine too much when you are affected by a crime. ”Shit happens”. A high enough amount of people just think it's downright low-class to demand ”revenge”.
And now to the minor offences. In Iceland, which is like Sweden but more, it is TECHNICALLY LEGAL to bicycle at the sidewalks. You get the society-to-handle theory? They didn't expect any chaos in the streets of Reykjavik, so they went for the ”freedom under responsibility”.
Stockholm activities that are technically illegal but that the police will not care about (no guarantees, though):
Bicycling at the sidewalks (if it doesn't look very unsecure).
Drinking alcohol in the street or in the park.
Peeing outdoors.
Jaywalk (as everywhere).
Examples of Stockholm activities that are technically allowed:
Eating, drinking and talking on your cell phone on public transportation.
Watching a crime without doing your best to prevent it.
Smoking when walking (unlike in Tokyo).
Saying ”knulla”/”fuck” in television
