I'm fine with it. He clearly knew what he was doing was illegal (he actually called his Dad and asked permission before doing it, telling him it was a once in a lifetime opportunity) and he was resisting arrest. Tase away.
That said, I think the rules should be different during rain delays when there are no players on the field. Let the guy slip and slide into every base on the tarp and then tackle him at home. No need for tasering there.
