Runner dives over catcher on tag play

[justanotherump]

First, it's clearly a dive. We could look up the definition and post it, but I think we are grown ups. Like I stated before, it does leave it up to the umpire's judgement whether the fielder dove 'over' the fielder or not. My opinion, from the not as grainy as has been made out to be video and the very clear pictures, one from the opposite angle, is that the runner dove over the player. So, regardless of why, I think the runner should have been called out. Everybody misses stuff on the field at some point.

Is it wrong to point this out and try to decide what could have been done differently, so we can learn and be ready if it happens to us?
