How to avoid incidents like last Saturday???

Now that we've all paid our respects to Leavander & family, it's imparative that we congregate and conversate about how these things can be prevented in the future....we, the fans, are the ones who pay our hard-earned-$$$ to view these types of events, therefore we are somewhat-responsible for coming up with some type of system/rule/method of trying to avoid these types of occurances..... it was pretty obvious to me and 3 of my buddies who don't even like boxing that the fight should have been stopped after the 9th round....then came the 10th....then the 11th.... should there be a system where fighters aren't alowed to come out for the next round if the opponent is landing at a high % or is out-landing the opponent by a certain # or %??? Should the doctor be allowed to stop the fight at any given notice? Dunno if that woulda helped on Saturday, but it's worth a thought.... I dunno, I understand that these things will always be a factor in a sport like boxing (I attended Barrera-Morales 2, where Pedro Alcazar passed 2 days after fighting Alejandro Montiel), but I do think that last Saturday could have been avoided.... any thoughts on how to improve our beloved sport????
