An assault weapons ban would stop the manufacture of many of the deadliest guns.  Yes a ban would not immediately take assault weapons off the streets but there would be significant long term benefits as highlighted by Connecticut Senator Joe Liberman "We ought to restore the assault weapons ban -- not to take anybody's guns away that they have now, but to stop the manufacturing of these weapons." [1] The ban would stop manufacturers from making the weapons and with the legislation improved from the 1994 version it would be possible to prevent the cosmetic changes that were made to keep guns on the market. [2] This would mean that prices both in the USA and globally would increase as there would be less supply. One positive result might also be help to change the United States’ position on the arms trade treaty which would further restrict global supply. [3] This would answer Mexican calls to cut off the supply of guns into the country that helps make the drugs violence in the country so deadly both by meaning less of the weapons are made and by helping to cut off the route through which weapons get into Mexico. [4] A ban on assault weapons would not fix Mexico but it would deprive arms smugglers of the closest, easiest and cheapest place to buy the arms used by the drugs cartels.
