Bump firing the rifle would be inaccurate if the shooter went through the whole clip with one or two pulls. This stock attachment allows for reasonably accurate burst firing. A gunman with an automatic weapon will not necessarily waste all of his ammunition with continuous, inaccurate fire. With very little training, he can learn to burst fire. This capability blurs the line between a military and civilian rifle. There is a video of the stock in action here [1]. It seems to me that someone with limited training would still completely outgun a regular police officer armed only with a pistol.
