I see dead balls
It seems I misrembered the shots Efren had, but I found them both. Neither was a hanger (I think another player had a hanger ruled against them).I don't recall the Efren incident but that sounds like appalling refereeing. The incident with Earl was unfortunate and probably a mistake but the fault lies with Earl because he knows the rules and called the wrong ball. If he had immediately put his hands up there was a chance he would have been allowed to play on. As it passed, he came across as an ass and so be it.
These things happen rarely, as do ridiculous flukes in non-call shot. Neither is desirable but good rules are.
