[Kill Bill] Vernita Green was a professional assassin. Even if she had been off the job for a few years to raise her kid, how could she miss her killshot on Beatrix?

I mean, I get that she might be rusty, and maybe knives and explosives are her specialty, not handguns.  But how do you miss from that close? This is like 6 feet away.  

Not as bad as Greedo missing, but might as well be.

I would blame the fact that it's in a cereal box while being fired. She had no way to line up the shot. She probably hid the gun there to be retrieved and used, rather than fired from inside, but knew she wouldn't have that kind of time at close range with Beatrix.
