Did Bishops Diss The Pope?

One thing you never want to do is leave the Pope hanging.

Check out this video of the Pope offering his hand for a shake to Bishops on a greeting line.  Bishop after Bishop let the Pope pass by without shaking his hand.  One or two may have missed it, but this seems a little fishy to me.

ht Mark.

I don’t like to read into things, but was this some sort of silent protest over working hours or something?  I haven’t seen a reception this icy since I told my wife I would be playing golf with my buddies all weekend.

So what is up with this?  Is this on purpose or is every Bishop here blind?
