Loss of life can be minimized by extending background checks to those who have a history of Alcoholism. Currently those indivduals who have been convicted of a DUI, DWI, and other alcohol related misdemeanors which are not punishable by 2 years in prison or a Felony punishable by 1 year in prison are allowed to purchase firearms.
These individuals would nomrally not be allowed to drive, why should they be allowed to purchase a firearm?
Organizations such as the ATF should be positively identifying purchasers of firearms to better trace criminals and enforce background checks.
