The Dutch Schools Prepare For New Year's Eve

From this week's Expatica website for English speakers in The Netherlands:

Dutch schools to prevent New Year arson
Measures include removing valuable equipment from schools and hiring security guards.
Dutch celebrate New Year with fireworks, riots
THE NETHERLANDS – Many primary schools are taking extra precautions to prevent vandalism and arson round the New Year. Last year, 25 primary schools suffered damage as a result of fireworks, vandals or arson. Five schools were burnt down, bringing the total damage to around EUR 25 million. The Association of School Managers is calling for precautions to be taken this year. Measures include removing valuable equipment from schools and leaving lights on over the holidays. People living near schools are being asked to keep an eye on the premises, while some schools are hiring security guards.[Radio Netherlands / Expatica]

It happens every year, and to me it seems crazy since normally The Netherlands is a very ordered society, like most countries. Why schools? Primary schools especially.

We'll have controlled fireworks displays (fireworks are banned here for private sale) across Australia, parties and fun. It's highly unlikely one car or building will be burned across our entire country.
