You seem to ignore the reason that the cop was involved in the first place.
We know that the women stole merchandise and hit the cop when he tried to stop them from going out the door and then ran from him when he ran after them. So we have theft, failure to stop and striking an officer. The girls were in pretty much trouble right there.
Here's your problem ~ it is REMARKABLY unusual for cops to run out into (presumably crowded) parking lots and shoot at unarmed women with children.
On the face of it this is a highly unusual case ~ so every single little sniveling trivial fact will be processed with a fine toothed comb over and over.
This case is going to Court TV (Real LIfe TV?). There's drama, pathos, adventure ~ leaping over cops, bounding through parking lots, being dragged while shooting, chillun's jumping and shouting ~ stuffing purses ~ WITH WHAT?
We start this docudrama with the young mother standing before the judge agreeing to never, ever go to a Walmart again ~ OH MY GOODNESS ~ what's not to like about this one ~ within minutes she's slabbed out and some forensic pathologist is trying to see what really killed her!
We could do a series on this ~ just change Galveston to Houston, adjust a couple of other words to fit the rhythm and we have a well structured themesong to go with it ~ try: >http://www.youtube.com/watch?v=xsHUgpSxMoI
