This is weird:

"COLCORD, Okla. (AP) - A 4-year-old boy was killed by a stud horse that jumped a fence and attacked him as he played in his front yard.
The horse bit Bailey Stockton on the head and body and ripped off an arm Wednesday.

The horse, owned by the boy's family, was grazing in a pasture near their home.

The boy's stepfather shot and killed the horse."

Well at least they took care of the horse in the correct manner.  

Poor horse. it probably had a reason for doing what it did. i doubht it thought to itself "hhmm.. gets to rip that little boy's arm off"

Yeah, I doubt the horse was thinking I'm going to fix him.  but stud horse can be SOB some times.  meaner than any pitbull.
