It is well known by properly educated people...
That in a gun fight--many of the shots fired do not
hit the target--this is a common phenomenon with soldiers in war, with
police and with private citizens in personal defense against criminals.
Another fact often overlooked--and deliberately so at times--is that in many cases of criminals attacking citizens--there is often more than one criminal--and many times there are gangs of criminals attacking citizens.
In fact much of the human crime involving firearms--comes from gangs--and much of that being in the inner cities, e.g., Chicago.
As such it will take more shots fired to eliminate the criminal threat.
The federal governments own statistics have conclusively shown, that the magazine restriction to just
ten rounds in the Clinton ban of 1994 to 2004--did not reduce crime; [crime rates were already declining]
and after the ban ended the crime rates continued to decline--with millions of formerly banned magazines sold and used and millions of formerly banned guns sold and used--crime rates declined.
