We do have surveillance cameras in certain areas. Gasstations, schools, shops. Most of them are there under the regulation that the images have to be wiped within 24 hours after they have been taken, unless there has been a crime the images need to be used for in those 24 hours. Then the images can be saved, till no longer needed, and they will have to be destroyed after that. As far as I know, the deleting of the images almost happens automatically. Also there have to be signs telling you that there is camera surveillance.
I can live with that.
Now and then there are voices to make things tighter. 9/11 works well as a tool to frighten people and let them hand in their freedom.
