Arson on Hudson School Grounds Saturday 21 May

It appears that sometime between Saturday after dusk and Sunday morning, someone or a group of people started numerous fires on the Henry Hudson School grounds: they lit up fires in the commercial garbage bins, burnt out the school ground garbages and set fire to the bulletin board.
A police report has been filed #VA1697504. An officer did visit the site already and has documented the damage. The police have also contacted VSB and will set arrangements for an officer to follow up on an investigation after coordinating with VSB/School Admin.
The incidences and severity of vandalism on our school grounds has escalated significantly in the past 8 months. I’d like to ask: Is it time to consider No Trespassing signs or School Ground closed after 10pm … violators will be prosecuted… or something like that? And way more lights on every corner of the grounds and all around the courtyards etc?
