Fair point, I had got a little gung ho with the napkin math.

I'm not the only one though, I double checked the "dozens" were all from the New York office and not actually weaseled from a nationwide list. Found their presumed source and it's 28 cases.

Which is including a large number of cases where prison corrections officers falsifying reports after inmates were assaulted weirdly comes under "falsifying business records". Lots of cases where it's a ancillary charge alongside class B felonies like insurance fraud or grand larceny. Less than 5 actually comparable cases where falsifying is the only charge, usually in connection with bribery.
