Yes, things will be quite bad during a couple of days in March 2014… :apologetic:

07-03 MAJOR UPDATE: the possession of cameras and telelenses is prohibitted during the NSS in the whole municipality of Gemeente Haarlemmermeer.
Police and military police can sent you away if you have a camera with you! This will be effective Saturday March 22 07:00 till Wednesday March 26 18:00

The mayor of the municipality explained this is a discouragement policy. I believe the police will only request you to move when using a camera is in case a place gets to crowded.

The authorities need a reason to sent you away. Just standing somewhere is not a reason. I am sure you will not be fined as long as you move on request of the police.
