You hate to speculate in tragic events like this, but most robbers I have ever read about don't go into bedrooms in the middle of the night brandishing a weapon. Seems really strange. Perhaps the intruders were doing this for the first time, but it doesn't make a lot of sense.
I was annoyed how this was portrayed from the beginning as a robbery or burglary (what's the difference) gone bad? The result is murder. Breaking a window and stealing a DVD player from the basement is a robbery.
Going into someone's bedroom with a brandished and loaded gun is murder if you ask me. Doesn't make sense to me unless they were totally unaware anyone was home OR wanted to get info from the Taylors, whatever. I sure hope the police are looking at it from a Murder angle and aren't guessing this is a bungled heist.
Stupid, tragic, and terrible, regardless.
