And at least here in the US, there was a little thing that happened in the 60's called deinstitutionalisation (http://en.wikipedia.org/wiki/Deinstitutionalisation). No one is locked up against their will for more than 48 - 72 hours at a time, and even then only if they are deemed to pose a significant threat to themselves or others. Not sure what the situation is like in Sweden, but i can't imagine it would be much different.
