Geir Jón Þórisson, the Reykjavík Chief of Police, is a well-known figure in Iceland. His level-headedness and calm demeanour has been credited with preventing actual rioting during the anti-government demonstrations of 2008 and 2009.
He is now retiring from policing, but on Culture Night he was downtown in Lækjartorg, meeting the people of Reykjavík. Several people posed for photos with him for the short time I was there. He is very tall, almost 2 metres, I think, and his son, who is also a policeman, is even taller.
