I live in Denmark and I trust my local law enforcement fully on an individual plane, they are quick, and responsive and professional. What I don't trust is the structure at the police-stations, lately the police has been stressed and the response rate has (again, according to the media where I live) been lowered significantly as the officers can't respond to every distress, but as far as professionally goes, when they do respond, they are professional, and witty. Which means they engage the people on a friendly basis and avoid potential confrontation.
