Police at PS library

Was walking back to my apt from the Y on Saturday at 1:30 p.m., and three police cars pulled up in front of the library at 6th Ave and 9th St - I had to get back to my kids, but was wondering what sort of incident had happened there? Does anybody know?

Oh My God!
Police surround the library!
Someone got an overdue notice and won't pay!
The sky is falling!
Police brutality!
Call Al Sharpton!

There is a Stephen King story about the library police that's pretty dramatic, but I think this whole business was probably something a little more serious than an overdue book.

Although my 8-year-old posited that the police REALLY REALLY REALLY needed a book. When I informed her that I didn't think that warranted sirens and three cars and the whole hoo-ha, she looked at me skeptically. Apparently I have never REALLY REALLY REALLY needed a library book.

There were a couple of ambulances there also, so perhaps somebody got sick?

They found out who checked out "Tropic of Cancer" and left it under a gym locker 20 years ago.
