Umpire is just watching the play. No LBR call.
How many umpires were there? It reads like there was only one...which gets back to the point regarding the shortage.
If there were 2, this could have / should have been resolved.
I occasionally work with sub-standard partners...I'm still glad they're there.
And we could go anecdote for anecdote about bad calls, bad coaching, bad parenting - it's not clear your example proves the "state of umpiring is terrible", anymore than my stories from a game last night show the state of coaching is terrible (and the state of parenting...yikes).
