I live near a yeshiva with a simcha hall. someone at a bar mitzvah in the hall blocked my driveway and had a placard that read “on official nyc police business”. If you are entitled to a placard, dont abuse it. I’m fairly certain this guy wont use the placard in my driveway again – not after I told him I called the local precint and asked what official business required someone with such a placard to block my driveway, and I gave them the license plate – I didnt, but let him sweat a little.
