Thanks for that 'Soup, I instinctively knew there was something wrong in this narrative if this guy was threatening and advancing and allowed to get in that close, it just seemed to me there were other options.

Plus, if this guy was unarmed, where's his (the cop's) other gear (like Tazers) and his partner (or is this guy flying solo?), and he's still in his patrol car, right? He can always Randy Moss his ass. What's he gonna do, punch my car? You could use it create distance to reengage or call backup.
They let this guy get in close, maybe by mistake maybe not, but once in that close the bullets flying is no surprise.
I'm guessing Ferguson doesn't have great training, maybe they pull from the same Academy or have transfers in from elsewhere, whatever.
Seems like they have more gear, guns, ammo and toys than brains...
