There are probably many more than most people realize.
Remember Jose Guerena in Arizona?
At least Jose got to live several years before he died. 
Remember 11 year old Alberto Sepulvida? Alberto was killed by a shotgun blast to the back while following police orders and lying face down on the floor during a SWAT raid. He was a seventh-grader at Prescott Senior Elementary School.
And I'll leave it at that. My patience and tolerance of WOsD warriors has been worn completely out. They have nothing but my contempt.
