We have seen the reaction of police in the United States to being videotaped by citizens in arrests and destruction of equipment. It may therefore be instructive to see how police in other countries respond to such videotaping like this officer in Sweden.

The snopes article, linked above, says the guy is an actor and not a real police officer. The snopes article even quotes JT regarding taping of police.
Please check Snopes on this. This was not a real police officer. How embarrassing — for you.
