Back in the latish 70's when I was applying to NYPD, they were recruiting many new folks to do undercover ops against various political organizations. I know one of my buddies, a Puerto Rican from the Bronx, was selected to do a UC op on Puerto Rican separatist / terrorist groups at the time.
I ended up going federal, but I was recruited in a similar fashion by my first agency. They had me going in on traditional organized crime targets as well as a 1% motorcycle club operating in NYC and Long Island. When that assignment was completed I was sent to the academy a few months afterward.
It seems that NYPD and the feds were doing similar ops to target what they considered "organized" threats.
