Assuming that email really was written by Scott Dominguez the District Attorney, I find it quite surprising. For starters, it's surprising that a somewhat public figure like that - someone who the public has entrusted with with gathering evidence and making irrefutable arguments to bring down criminals - would willingly churn out a piece of writing so poorly-written and naive. We expect lawyerly types to at least be circumspect - so, he could have said that Meza was a wonderful guy who did these generous things for him years ago, and left it at that, rather than stating so forcefully that he also definitely did not cheat. By saying that, he is setting himself up to be shown a fool. Anybody that takes the time to watch Meza lurking at the side of the road before jumping into a race in progress is going to be like, great - we've got an idiot for a D.A.
Googling Scott Dominguez DA indicates he works or worked in the White Collar Crime Department, so he would have even less of an excuse for being blinded by loyalty and affection. He can't use the excuse that he was too trusting and didn't think a doctor/philanthropist could possibly cheat. He of all people should be familiar with the type.
As another poster or two mentioned, Dominguez's writing leaves a lot to be desired considering that it comes from an apparently successful lawyer. Besides a grammatical mistake that was pointed out earlier, he says (among other things) "I never ran faster than the number three runner on Varsity", which is an odd and imprecise way of putting it. Does he mean he actually was the number 3 runner at least on some occasions (in which case it is poorly worded)? Because the literal meaning of the sentence is that he never ran a time that was faster than the actual #3 runner, which could mean he was the #4 runner or the #15 runner. I would have thought such imprecise language would be anathema to a professional lawyer.
Dominguez babbles on "Dr. Meza is FAST when it comes to long distances, and he doesn't cheat." But he ran with him over 23 years ago! Does he still run with him? If so, he doesn't mention it. And if he doesn't, then presumably he realizes that someone who is fast in their mid-40's isn't likely to still be fast at 70. And how does he know he doesn't cheat? Does that kind of declaration fly in the courthouses where he makes a living?
The thing is, if this statement truly comes from Dominguez, he KNOWS it is riddled with faults. He has to know, because while a law school graduate might not be the greatest person, there is a certain level of intelligence required (or so I have been led to believe). And if he knows his statement his misleading, then he is guilty of willfully deceiving the public.
