I also read a possible reason he doesnt want to talk to police is to not lie to them. He legally does not have to talk with them, he has the right under 5th amendment and if he has something to hide he cannot get in trouble if he doesnt talk to them making up some story. Best to stay quiet.
In any case it really isnt a big deal, he got in a fight with his wife, so what. But his wife could be a husband beater maybe with a better long iron shot than Tiger, LOL
