The tough approach taken by Mr van der Laan ... reflects hardening attitudes to routine anti-social behaviour that falls short of criminality

I have grave concerns regarding governments taking this action. The point to formalized laws and courts is to ensure that the rules are clear, and not abused. A system like this removes the clarity of having predefined laws; anti-social behaviour is defined after the fact opening the system to huge abuses.

Effectively, people of Amsterdam can be jailed on undefined grounds.
