Lately, mayors’ powers for maintaining public order and safety have been considerably extended, and even more powers are in preparation. These powers must enable the mayor to act quickly against public order disturbances and security threats. The novelty is that the mayor may conditionally use and exercise these new powers preventively against groups of rioters. Their freedom of action and their privacy can also be considerably curtailed. This means these powers have to be used carefully and reluctantly. If the mayor overdoes the crimefighter role, he/she may lose the public’s confidence.
