Did you know that a cobblestone street was stolen in New Jersey in the late 1970's while the police were actually directing traffic?
Thieves were digging up the stones with a front loader and the Newark cops came by, noticed them and couldn't figure out why one of their off duty brethren wasn't picking up some overtime, so the officers signed out, directed traffic and put in for overtime themselves.
The paper I was reading did not say if the officers got paid the overtime.
