It is a start... Then we give local law enforcement greater opportunity to do their job without having to encounter as many assault rifles...
Military-style semi-automatic firearms (so-called assault weapons) do not differ materially from non-military style semi-automatic firearms (one bullet is fired for each pull of the trigger) and are no more powerful than other semi-automatic weapons. Further, a bullet fired from a semi-automatic weapon is no more powerful than one of the same caliber fired from a corresponding non-semi-automatic handgun, rifle, or shotgun. In fact most assault weapons are less powerful than hunting rifles. For example, the AR-15 which is a semi-automatic version of the military's rifle (M-16), is a .223 caliber rifle. Rifles of this caliber are often forbidden from being used to hunt deer because this small caliber bullet is more likely to wound the animal (and allow it to escape and suffer a slow death) than the more powerful .24 to .30 caliber bullets normally used in deer hunting rifles. (An example of rifle caliber restrictions are Tennessee deer hunting regulations. Click on "regulations" in the frame area.) Assault weapons are not the weapons of choice among drug dealers, gang members or criminals in general. Assault weapons are used in about one-fifth of one percent (.20%) of all violent crimes and about one percent in gun crimes. It is estimated that from one to seven percent of all homicides are committed with assault weapons (rifles of any type are involved in three to four percent of all homicides). However a higher percentage are used in police homicides, roughly ten percent. (There has been no consistent trend in this rate from 1978 through 1996.) Between 1992 and 1996 less than 4% of mass murders, committed with guns, involved assault weapons. (Our deadliest mass murders have either involved arson or bombs.) There are close to 4 million assault weapons in the U.S., which amounts to roughly 1.7% of the total gun stock. If assault weapons are so rarely used in crime, why all the hoopla when certain military-style-semi-automatic weapons were banned by the Crime Control Act of 1994? A Washington Post editorial (September 15, 1994) summed it up best: No one should have any illusions about what was accomplished (by the ban). Assault weapons play a part in only a small percentage of crime. The provision is mainly symbolic; its virtue will be if it turns out to be, as hoped, a stepping stone to broader gun control.
It goes deeper than that Arnie. Assault weapons have been targeted (no pun intended) by the Left because they know it'll be a militia of assault weapon toting white guys bringing down the Obama/Smits Afro-Mexican coalition in 2016. That'll be around the time white folk have their homes confiscated for reparations and a special Gringo Tax is enacted whereas not only are "illegals" now legal but they're fully taxpayer subsidized.
