Two, I believe the crux of this lies between your point of view and that of the callous reply left on FO.  6-14 kids die every year playing high school football, boxers die in droves, football players, etc.  It happens.  But when money is involved, even death isnt gonna change much.  

Sammy's death does need to be investigated.  This is the first true death in MMA, and as the first, it needs to be investigated more thoroughly than your local traffic accident.  I dont think it should be brushed aside, but we shouldn't be throwing Molotov's through the PM's windows either.  Let those with more qualified minds work through it, as they will.  Then when the data is in, any rules that need to be changed will be. I'm sure Keith Kizer, Armando Cantseeya, and Larry's replacement are all over this.  

As you oh so correctly point out, med insurance and critical care insurance need to be MANDATED at every MMA event everywhere.  That and a modest life insurance policy.  With the proven safety of MMA, I'm sure the mathematicians at every insurance company will be lining their executives up to get in on that action.

For my own 2c, medical exams need to start 2-4 weeks out before a fight.  Base line data needs to be established so a doctor knows what the hell he's looking at.  Any doc will tell you, with out prior history, cat scans, blood work, and EKGs are just about meaningless when trying to gauge someones current health.  I have low bp.  Always have.  Whenever I go to a new doc, they look at me like I'm about to die.  Nope, it's just the way my shit works.

I'm waiting for this to happen before the pre-fight clearance can be re-evaluated.  There are some words from his wife which suggest he had a pre-existing brain problem.  This, if true and relevant, would lead us in a good direction.  Concussive trauma and cranial bleeding would be good things to test for predispositions toward, if they're not already being tested for.  But this is just speculative until we know more.

I want to make this sport as safe as possible too, but jumping the gun will get us running in too many directions.  Unfortunately, we also don't have anyone to actually find this information for us.  Without someone like Dana pushing for answers and medical review this ain't gonna happen.

My callousness isn't towards Vazquez' death, which I consider damned sad.  My callousness is towards your attitude about it, which I consider to be nothing more than over-wrought hand waving.  

"The nightmare has finally arrived. Amidst all the sanctioning processes and oversight, a fighter in professional competition suffered defeat. Lethal defeat. We knew the system wasn't perfect and now we have proof. Worse, now "they" have proof, too. "They" being the bitter enders of critics, politicians and pundits slandering the sport for ratings grabs"

That is tacky as hell, a bald-faced ploy use this tragedy to grab at the emotions of the reader to further your own opinions.  If you want to say that we should use this opportunity to reexamine regulations, fine.  But depending on the emotions involved in this tragedy to make that point is disgusting.

As for the content itself:

First, my comment that asa repeated: until we know exactly why he died, we can't analyze any way in which the requirements should be improved.  That is completely true.  The current regulations have been put in place by professionals more qualified than you or I, and there have never been any deaths in regulated MMA until now.  Vazquez' death may have been an unforseeable fluke, it may have been a problem with the rules.  But until we know the cause of death, it is irresponsible to be calling those rules into question.

Second is in response to this:  "When enough information is collected and processed through the minds of those who are far more familiar with these sensitive subjects than I, then I hope there will be appropriate opinions and suggestions issued for everyone to evaluate. In this world of instant opinion, we are expected to have omnicompetence over issues. But I don't have that."

Neither does anybody else.  Thats why we want to WAIT before we start pointing fingers.  You bet I'll pitch a fit if it turns out that his death was both preventable and something that should have been forseeable.  If it was preventable and unforseeable with current regulations, I'll expect the regulations to be improved to a reasonable level.  If it wasn't preventable, or else unforseeable with any reasonable regulations, then I won't say anything at all.  But I'm going to wait until I have the information necessary to pass any judgements.

Third, you defend yourself by asking what you can do, you have a website.  But that applies to most of the MMA media.  Guys with websites and tenuous contacts within MMA organizations.  Not people with the time and resources to actually investigate what happened.  They are leaving that in the hands of people who ARE investigating what happened.
