FBI Homicide Table
It appears that our government is just as efficient as ever. More people are killed from clubs, hammers, etc, than rifles in the statistics that we're given. Hell... more people were killed from punching and kicking than with rifles in 2011.
"Assault Weapons," are not split off from the other rifles in the chart, so I'm sure that the numbers of crimes involving these firearms are much lower than the total number given.
According to the government's own crime statistics, "Assault Weapons" are not a problem. Yet, somehow we really need a ban?
Their efficiency is only matched by their honesty.
