One from Finland here.
Police are a lot more lax about it here... I heard from the people I play that they got a "permission" from the police to airsoft when someone called them about airsofters shooting at windows in their old place (though my friends assure it absolutely was not them, even accidentaly or otherwise. There apparently were other airsofters using it too). When the police came to talk to them, it appeared they were apparently annoyed having to deal with "kids playing war" and basically told them "go play in that other forest over there".
It's still not exactly what I consider legal, and now that practically everyone of us is old enough to be charged, I think we should move from there. The problem is that aside from couple more enthuastic guys in the group, the airsofters I play with are lazy as hell and hardly get their asses there (games get constantly cancelled because only few would come or because the guy X is not coming his friend Z is not coming whose friend Y won't come if X won't come), let alone *gasp* a place you need to change a bus once to go to.
Sigh... I need to get to know other airsofters from my area in the next scenario if any show up.
Still it's pretty lax with the police apparently, despite that Finnish airsofters never use orange tips.
