Meaning guys get put on and taken off the shelf and its not news worthy.
Daily meaning it happens and we have no way of knowing it happened essentially. (Unless a made guy flips)
The feds very rarely come out with this info because no one really cares.

Al Trucchio we think was put on the shelf 10 years ago he was a huge earner, his dad was and is very respected.
He spoke out of turn

Is he still on the self? We dont know.

Ernie Grillo was put on the shelf under Gotti
Was taken off at some point and then put back and then taken off

There are what 8 families left? Guys mess up all the time, they no longer get whacked when they mess up, those guys get put on the shelf.

Every year who knows there are probably a handful of guys that get put on the shelf, at the same time guys get taken off the shelf.

Nobody gets killed anymore so when people fuck up they get put on the shelf.

Its not like a murder where someone is dead.
If someone gets pinched there is a court case we know about it.
Its not really an event like a making ceremony that the feds are dying to find out about.

There is no foot print left of the event really.

So when I say it happens daily it is not a literal term its more figurative to describe it as a whole.
