The title says it all: Is it legal to film and record anything in public areas in Sweden (e.g. using a mobile phone)? Starting from roads/trees/object to people and especially the police (e.g. in a case when police want to possibly arrest somebody and use violence).
Any help would be appreciated.
P.S 1: I know it's illegal to do so in private areas.
P.S 2: I know it's also illegal to do so in metro or commuter trains without permission. However, I'm not sure whether I'm still allowed to film e.g. police in there or not.
