Either I'm just having a bad day or stupidity is running wild in the news business today. Here's another article with a "DUH" response to the question in the headline: Authorities seek reason why Turlock man beat his toddler to death
One passerby who grappled with him said he was muttering that the boy had 'demons' in him.
There are three possible answers to the stupid question - WHY?:
a) The guy was some kind of religious nut
b) The guy was some kind of schizophrenic mental case
c) All of the above (my vote)
