Police is not supposed to be neutral, since it’s part of the executive branch of government.

Keeping it up will be tough but there seems to be a lot of motivation there. I think it’ll be kept up until Prinsjesdag.

The legal/administrative situation is interesting. The Public Assemblies Act and the ECHR don’t categorically rule out blockades and this specific spot isn’t nearly as disruptive as some make it out to be. The mayor chooses to ban rather than facilitate, has everyone arrested, but the public prosecutor doesn’t actually charge because people get acquitted or released without sentence by the courts.
