Does anyone know how to shoot straight in this movie

Ever since the Gena Davis character finds out she's an assassin nobody, including her knows how to shoot straight. If any of the 9 or 10 "trained" killers could have just hit their mark once she would have been dead many times over. The very first fight scene alone had the guy miss 4 or 5 times basically with a rocket launcher with her in clear sight. Then by instinct she grabs a gun and shoots at the Samuel L. Jackson character right in front of her and misses by about a foot. Hard to believe in this.
