OK, that's weird. It doesn't entirely come as a surprise that they would have an international arm, since they are home to the UN and were the most visible target of the most prominent international terrorist attack. But having that money come anonymously... that's suspicious.
The "anonymous donor overseas placement" system is clearly a means to launder bribe money into holidays for officers. Anonymous "donations" to police are so obviously corrupt they might as well hang up a sign.
I mean it wouldn't surprise me if the NYPD had a liaison directly with FBI field offices outside of the country, since the stakes are so high and tight integration could save lives. It would also be weird if the NYPD were operating much more directly than that.
