It appears that on the American side the guys that are left are comfortable and not looking to take unnecassary risks,
I.E they aren't going to be chasing people over a $1,000 gambling debt or a few thousand in loan shark money.

No Nickel and Dime stuff
Probably two-three layers away from drug money.

Also the FBI and local L.E. wrote them off including the local media.

For a crime family could you ask for a better scenario?

Imagine the FBI and N.Y.P.D. and local media saying the Columbo's are dead, we are not pursuing any more cases, we have no C.I. there is nothing to investage, We are closing all open cases.

That would be the jackpot.

How does anyone know what's going on in Buffalo?

Wouldn't the above scenario be PRFECT for re-building a crime family?
