Police Reports for many years ago

[Lynn-ji]

I worked for the U.S. Embassy in New Delhi in the late 60's and lived on the Embassy compound.    I am having trouble getting info from the Indian Consulate in Washington.    Their online form seems to be for Indian citizens.   Does anyone know if Immigration requires police reports from so many years ago as I may not be able to get one.  (I don't want to send $40 to the Ind. Consulate and find out it's not possible to get one - maybe not for Embassy personnel anyway).
