Years ago, probably pushing eight now, I noticed Franklin testing Finderne Squad. If I recall correctly, they identified as 275; I think it was a daily test but it may have been weekly. I didn't notice that they ever stopped.
Back then I asked around a little and heard that it was for mutual aid. I don't have the current mutual aid list but would expect Finderne, as an adjacent squad, to be routine backup for that end of Franklin if 53/71, RWJ-SP, and Rutgers are unavailable. Which, I guess, makes it not-so-routine, considering how many agencies are ahead of them.
