Couple of things that boggle my mind about all this - First, why did it take four years to get the tribunal? That seems fairly excessive. What was she doing in the meantime? Paid suspension? Placed at a desk?
Second, is she that bad of a shot that she missed a dude who was maybe 15 or she feet away? I know it isn't easy hitting a target with a handgun, but this seems like very poor marksmanship. And, if she wasn't trying to hit him, was it a warning shot?
Either way, discharging your firearm like this should be a major investigation. I don't understand how they can wait so long to hold her accountable for this. Would it be faster if she hit him?
