Someone did something to stop it. You better believe.
Someone had earlier remarked to the effect of “Why didn’t his family control him?” My point was that he probably didn’t appear dangerous or even deranged until all of a sudden when he just went off. And some psychiatric cases can be like that. Little or no warning.
This is why the medical examiner will be examining his brain “with a fine toothed comb”. He could find a tumor, or unusual blood vessel growth, signs of schizophrenic degeneration, small strokes, who knows?
Yes, the families were in the right to defend themselves; but at the same time, their attacker may have been so out of it that he can’t be entirely blamed either.
There is a frustrating point with some mental illness where “the lights are on, but nobody is home”; where they seem rational and sane, but you might as well be talking to a wild animal. The humanity is no longer there, either temporarily or permanently.
